Need a kids' water bottle? To determine the best 12 products of 2021, we dove into the world of water bottles for kids, researched the market, then purchased more than 30 promising contenders to send through testing and side-by-side comparisons. Keeping your child hydrated while on the go is essential, and a water bottle certainly helps this effort. With various bottle types available, some being more convenient and healthier than others, our testing focused on necessary factors, like leakage, potential lead exposure, weight, ease of use, durability, and more. We are confident that there is a water bottle in our lineup that will meet your needs and budget. So, take advantage of the insider details and buying advice to make an informed decision.


Best Overall Kids Water Bottle

Hydro Flask Kids Wide Mouth

Volume: 12 oz | Weight: 0.6 lbs
Double-walled insulation
Easy to clean
Carry loop
May not fit in cup holders

The HydroFlask Kids Wide Mouth is an insulated stainless steel water bottle that does a superb job keeping liquids cold all day long thanks to its double-wall vacuum insulation. This smart-looking water bottle is durable and top-rack dishwasher safe; however, we recommend handwashing for longevity. Thanks to its wide-mouth design, cleaning with a bottle brush like the OXO Tot Brush should be a breeze. As for the straw, we suggest a small brush for better cleaning. The straw lid version only comes in a 12-ounce size, a volume that perhaps is most compatible with younger children. A larger size may be a better choice for active older children who dash to and from sporting events or activities. In this case, HydroFlask offers a larger size, but with a Flex Cap or Hydro Flip lid.

One drawback is that this water bottle may not always be compatible with most cup holders (think car and bike holders). It is also one of the most expensive water bottles in our review, a factor to consider for those on a tight budget. However, we think this insulated stainless steel water bottle with a straw lid is hands-down, an all-around excellent kids' water bottle. Plus, Hydroflask is built to last and has a lifetime guarantee, which means this water bottle is arguably worth the price of admission if your budget allows.


A Classic Reinvented

Klean Kanteen Insulated Kid Classic

Volume: 12 oz | Weight: 0.6 lbs
Chip-resistant exterior
Kid-friendly lid accessory for purchase
May dent

For kids with on-the-go lifestyles, the stainless steel Klean Kanteen Insulated Kid Classic keeps contents cold or hot for an extended period while you bounce around from one activity to the next. The insulated design makes the bottle sweatproof, so your bottle won't be sweating more than your kids after playing in the summer sun. Klean Kanteen has recently updated its design to make the exterior more chip-resistant than the old version. We also appreciate that Klean Kanteen company uses eco-friendly practices and creates and improves products that will last.

This water bottle features a twist-off lid, and if screwed on too tight, it can be challenging to remove for younger children. Plus, wrestling it off can invite spills. We think you will appreciate the Klean Kanteen Sports Cap 3.0 for its ease of operation as an alternative to the twist-off lids. But, it is a purchase in addition to the water bottle. The insulated Klean Kanteen also doesn't feature a silicone boot, so even with improvements to its finish, dents and paint chips may happen over time. Nonetheless, we think this water bottle with excellent insulation will last a long time. For younger children, you may want to consider the lighter and non-insulated version called the Klean Kanteen Kid Classic Sport, which includes the Sport Cap with a silicone spout, and it may be more comfortable for little ones to manage.


Stainless Insulation at an Affordable Price

Simple Modern Summit

Volume: 18 oz | Weight: 0.7 lbs
Two lids
Priced well
Average insulation

The Simple Modern Summit is an insulated stainless steel water bottle available in a range of attractive powder-coated colors, along with sizes (14 to 64 oz). We tested the 18 oz, which we think is big enough for kids without being overly large or heavy, and it is durable enough to withstand bumps and drops. We appreciate the Summit's functional affordability for insulated stainless with the inclusion of two lid styles, a steel twist top (plastic on the interior), or a user-friendly flip-top.

While this option is insulated and will keep beverages colder than a non-insulated bottle, it doesn't keep ice frozen as long as others compared to other contenders in our review. Also, given the steel construction, it weighs more than a plastic water bottle. That said, the Summit is a great bottle if you're looking for a stainless steel product that is durable yet affordable.


Best Plastic Bottle

Contigo AUTOSEAL Trekker

Volume: 14 oz | Weight: 0.2 lbs
Dishwasher safe
Difficult button
Can break easily

The Contigo AUTOSEAL Trekker is an excellent solution for kids who tend to spill (possibly all kids, right?). This kid water bottle has a unique and innovative spout system that requires the child to push a button on the lid's back to open and release the liquid to drink. This design means no accidents or spills from a top that isn't screwed back on or leaking from a straw, making this option perfect for car rides, couch sitting, backpacks, or a nighttime sip of water. Kids love them because they are a step-up from a sippy cup, plus lightweight and easy to carry. The entire bottle - lid and vessel - are dishwasher safe, though the top does have nooks and crannies that will need some inspecting and scrubbing with a straw brush.

While testing, it was apparent that this product takes some coordination and could be challenging for younger kids to manage. Children with smaller or weaker hands might struggle to apply enough pressure on the button and drink simultaneously. Our four-year-old tester was a pro in minutes after being shown what to do, but the three-year-old tester had more difficulty and sometimes grew too frustrated to bother. This bottle may have durability issues as users report the bottle breaking. The body is plastic and may hold up reasonably well, but drops at the right angle could damage it. If you are looking for a thirst-quenching, spill-proof option, this press-to-drink product is a top-contender.

Recall Notice Does Not Apply
The recent Recall Notice: Contigo Kids Cleanable Water Bottles does not apply to the Contigo we reviewed in this roundup of products. The recall concerns a bottle and spout style where the spout can detach and pose a potential choking hazard. The Contigo in this review does not have the same spout design and is not included in the recall.


Our Favorite Glass Bottle

Lifefactory with Active Flip Cap

Volume: 16 oz | Weight: 1.1 lbs
Silicone protector
No leaching concerns
Dishwasher safe
Lid shutting problems
Potential leaks

Available in multiple bright colors and various sizes, the Lifefactory with Active Flip Cap is a glass bottle with a medical-grade silicone sleeve that adds a layer of protection to the bottle and helps prevent breakage from accidental drops. The silicone sleeve provides a grip-able surface for young users. Glass containers are inert, so there are no worries about leaching chemicals or imparting flavor to the bottle's contents. It is also super easy to clean with a bottle brush or in the dishwasher.

There have been a few complaints about the Lifefactory, primarily related to lid issues. Users report that over time the lid doesn't stay closed, the cap can be easily nudged open in a bag resulting in leakage, and that the cover drips even when adequately attached and sealed. Also, weighing over a pound, this water bottle is one of the heftiest in the group. It could be difficult for some younger users to carry or lug around in a backpack. But, if you are looking for an eco-friendly inert bottle, then the glass Lifefactory is a quality option.


Our Favorite Plastic Straw Sipper

CamelBak eddy Kids

Volume: 12 oz | Weight: 0.3 lbs
Carry loop
No insulation

Sporting fun graphics, the CamelBak eddy Kids catches kids' attention, and parents appreciate its lightweight and spill-proof design. The lid features a silicone bite valve, which requires a flip, bite, and sip to drink. The valve is shielded from debris when folded and is essentially spill-proof. We appreciate the transparent plastic, making it easier for parents to monitor how much liquid their child is consuming.

We are not plastic fans and consider it less desirable than stainless steel contenders, given the potential of this material leaching chemicals. So, we prefer to use this water bottle when weight matters, such as in a kid's lunchbox or while hiking and traveling. It lacks insulation, which is not a deal-breaker, but a factor to consider if you seek this feature. There's a couple of parts (bite valve, straw, bottle, and top) to keep track of, and it may take an extra minute to assemble and disassemble this water bottle before handing it off to your child. We also suggest using a straw brush to clean thoroughly. Nonetheless, if you seek a lightweight and cute water bottle, we think this product may be a match for your needs.


Best for Travel and Hiking

Vapur Shades

Volume: 0.5 L | Weight: 0.1 lbs
Hard to dry
Leak potential

If you are looking for a compact, lightweight kid water bottle from 0.5 to 1.5 L, the Vapur Shades may be what you want. We tested the 0.5 L size, weighing only 0.1 lbs, making it an ultra-light option perfect for on-the-go uses. We recommend the 0.7 to 1-liter capacity for ages seven years and up, as older children will need more water for better hydration. When empty, the vessel collapses and rolls up for convenient storage in small packs or some pockets, making it an ideal way to stay hydrated while traveling, skiing, hiking, and sightseeing. This kid water bottle can store in the freezer for extra cold water that melts throughout the day. It comes with a carabiner for quick attachment to almost any backpack.

While this product is easy to wash, we stress the importance of drying it thoroughly before storing it. If the drying step is forgotten or not thorough, there is an increased risk of mold or bacteria forming inside the bag. Propping the bag open is helpful. Also, double-check that the lid is on correctly and snapped shut to avoid potential leakage. If you want a small and portable container for your next adventure, this unique, innovative "anti-bottle" is an attractive choice.


Attractive with Innovative Lid

CamelBak Chute Mag

Volume: 12 oz | Weight: 0.6 lbs
Multiple sizes/colors
Magnetic handle lid
Good at preventing leaks

The CamelBak Chute Mag is a vacuum insulated stainless steel water bottle available in various fun, bright colors. The kid version of this bottle is 12 ounces, but if your little one's thirst demands a large swig, bigger sizes are available. The twist-on lid is excellent for preventing leaks, and it recently experienced some upgrades with improvements to the threads to decrease leaking. This water bottle also showcases an innovative feature that others in the competition do not have. A magnetic lid connects to the bottle keeping it from flopping in your face while drinking. We genuinely appreciate this practical design choice.

The lid for the Mag is dishwasher safe, but the bottle should be hand-washed, and due to its shape and size, a bottle brush is the best way to ensure it is thoroughly clean. While handwashing isn't a deal-breaker, and we suggest hand cleaning for all bottles, it can be a bothersome step for some parents who are crunched for time and appreciate a quicker fix. Another drawback is that this bottle is one of the more expensive options we tested, making it a poor choice for parents on a budget. However, it should last a long while, and the cost is more reasonable when you consider the longevity of use. When it comes to leak prevention and innovative lid design, we were delighted with this kid water bottle's overall performance.


Budget-Friendly Straw Sipper

Zulu Torque

Volume: 16 oz | Weight: 0.4 lbs
Locking lid
Not insulated
Can leak

The Zulu Torque is a durable plastic bottle free of BPA, phthalates, PVC, polycarbonate, lead, cadmium, and latex. The flip-top and straw make it easy for little hands to open and use. The plastic bottle has a silicone sleeve, an added layer of protection from accidental dropping or falls. The lid conveniently locks to prevent unintentional opening when carried in a bag or backpack.

A drawback of this water bottle is its lack of insulation, and this is something to consider if you want to keep your water cold all day. Also, there is a small hole below the straw to keep air flowing while drinking. If the lid is left open and the bottle tips, water can flow freely through this opening. It is helpful to lock the bottle while not in use to help keep this from happening. The Zulu is a decent option for kids who want a straw spout without the heft of a stainless steel bottle.


Nice Insulated Stainless Straw Sipper

Thermos FUNtainer Spout

Volume: 16 oz | Weight: 0.6 lbs
Good design for cleaning
Keeps contents cold
Good quality
Parts can wear out
Requires lid for leaks

The Thermos FUNtainer Spout is a double-walled stainless steel insulated water bottle that combines a sleek design and convenience. The insulation does an excellent job of keeping drinks cold for up to 12 hours (not for hot liquids), and the slender design is just right for little hands and cup holders. The lid button is user-friendly for straw access. The bottle is made with quality materials and feels durable enough to last for several years.

There are more parts to the FUNtainer than most of the competition, but they effortlessly disassemble and are cleanable with the help of a bottle and straw brush. Even though we like the quality of the container itself, the straw can wear out over time, especially if your little one has a habit of chewing. While the 12 oz style has replacement straws, we were disappointed to see that Thermos does not offer it for the 16 oz bottle. Also, while it does an excellent job preventing leaks with a closed lid, water flows freely through the straw with the top open, so it isn't leak-proof. So, if the button is pushed accidentally while in a bag, you could end up with a wet mess, and truthfully, no one has time to deal with that. But, given its quality construction and ease of use with various optional kid-friendly designs on the bottle, this bottle is a popular choice.


Double Leak Protection

Nalgene OTF

Volume: 12 oz | Weight: 0.3 lbs
Seals well
Few parts to clean
Difficult to close

The Nalgene OTF is Tritan plastic, and it is BPA-, BPS-, and phthalate-free. The OTF claims minimal leaking with a top that has a double latch system. This system includes a plastic piece that clicks on the base from the lid and a metal clip that secures it. This vessel has convenient grooves in the bottle to make holding it more manageable for little hands, and it is also durable and able to withstand drops reasonably well. The basic design is convenient for cleaning with few parts and a wide mouth opening for a bottle brush.

This bottle can be challenging to close. Clicking on the top part of the lid to the lower piece can be a pain for an adult, so it is even more challenging for small hands. It takes more pressure than we would have expected, and it only works if you line it up correctly, something little ones may forget or struggle to do. While older kids may fair okay, preschoolers could need some assistance. Another concern is that if the bottle is not full of liquid and the lid is left open, it will topple over. Despite its functional drawbacks and challenges for younger users, the leak protection that this kid water bottle offers is hard to beat.


The Classic Collapsible

Platypus SoftBottle

Volume: 0.5 L | Weight: 0.1 lbs
Lightweight & collapsible
Easy to store
Not the best for younger kids
Too small for Ice cubes
Harder to clean

The Platypus SoftBottle, available in 0.5 and 1-liter sizes, is a light, collapsible plastic reservoir that comes with a nonattached twist cap or attached push-pull cap (Platypus SoftBottle with Push-Pull Cap). Like the Vapur Shades, it is an excellent option for outings when you want to avoid carrying extra weight. It stores flat, or you can roll it up and store it in tight spaces. With a low cost and weight, this option is suitable for little ones who don't want to lug around a heavy bottle in their lunchbox or backpack.

There are a few downsides to this collapsing bottle. It can be a bit awkward to drink from as it requires two hands - one for the mouthpiece and the other holding the rest of the bottle. Also, the mouthpiece is too narrow for ice cubes, and it makes cleaning a challenge. While a bottle brush fits through the opening (just barely), it is hard to reach the bottom for scrubbing. So, while a daily rinse is necessary, a deeper clean with baking soda and lemon juice should be done regularly, making it one of the higher maintenance options in this review. It will also need to be propped open on a bottle rack to dry. We recommend trying the Platypus DuoLock SoftBottle, a more complicated flip cap with a lock for older kids. This bottle has a wide opening without the lid and is much easier to clean. Its size is greater, and therefore, more appropriate for a kid-size thirst.

Update: The Platypus SoftBottle is no longer available in 0.5-liter sizes, and the updated version will have different graphics than previous seasons. Otherwise, the product material and design remain unchanged.

Not Recommended: Notably Disappointing

Reduce WaterWeek

Quantity for cost
Strong plastic off-gassing odor

The Reduce WaterWeek bottles offer five water bottles for the price of one, which looks like a great deal on the surface. Unfortunately, the bottles emit a strong plastic off-gassing (or outgassing) odor that makes them a product we don't recommend. Off-gassing is the release of volatile organic compounds (VOC's), which are linked to numerous potential health problems and are a result of using certain chemicals during the production of the bottles. Upon opening these bottles, the odor was powerful and offensive. After allowing them time to air out and washing them multiple times, the strong "plastic" smell was still in full effect and ridiculously strong. After filling the bottle with water, we discovered the water became "flavored" with an off taste similar to the smell. Despite the company claiming that the bottles are BPA-free (and possibly phthalate-free), it is off-gassing something as many chemicals outside of BPA can and do. There is a flavor being imparted to the water after it sits in the bottle. These issues give us pause and puts the WaterWeek squarely on our not recommended list. Other chemicals in plastics can cause problems, such as PVC or vinyl and BPS (a substitute for BPA). Some of the potential health concerns linked to plastics include dizziness, nausea, allergies, asthma, endocrine disruption, and cancer. For additional information on BPA, phthalates, and PVC, check out the Children's Environmental Health Network or EcoWatch. While research concerning the effects of plastic on the human body is ongoing, there is enough information available to confirm safety concerns. We prefer to limit children's exposure to these chemicals whenever possible and encourage parents to strongly consider products that use stainless steel, glass, and silicone over plastic.

Why You Should Trust Us

Leading our roundup is founder, Dr. Juliet Spurrier, a Board Certified Pediatrician, a Fellow of the American Academy of Pediatrics (AAP), and a mother of two. This Mom-in-Chief uses her background, education, and experience to guide product selection and develop BabyGearLab's safety and testing standards. Also contributing to our water bottle review is Senior Review Editor, Wendy Schmitz. Wendy is a mother of two and holds a degree in biology with a concentration in chemistry. Her education provides a unique perspective on water bottle materials and potential concerns over plastics and their associated endocrine disrupters. Wendy has been involved in our sippy cup and water bottle testing since our first water bottle review in 2014, contributing to the beginning stages of testing development and review process. Since the beginning, Wendy has researched and reported on over 60 cups and water bottles. She regularly performs background research on the use of plastics in products containing food and liquid for human consumption. It is safe to say, Wendy's education, background, and Mom time influence product selection for testing with ease of use, safety, and potential for leakage in mind.

Finding the perfect kids' water bottle took over 80 hours of research and testing. Our review team assessed each product for leakage, potential lead exposure, weight, ease of use, durability, and more. Besides hands-on testing, we performed side-by-side comparisons to find the best performer.

Analysis and Test Results

Our analysis began with extensive research of over 60 kid water bottles, and we narrowed the selection down to the top contenders. Kid water bottles come in different varieties. Styles include insulation, sport tops or straws, as well as stainless steel or plastic. How each bottle performs and whether or not kids will use them depends on the ease of use and leakage. While the differences may appear minimal, bottles can function differently, and some are more challenging to use than others.


Weight is an essential factor to consider, especially when your little one is carrying it around. Is the water bottle going to school in a backpack already full of heavy books? Or will it mainly serve as a spill-proof solution around the house? Is it mostly for sports practice and outdoor activities? How you plan to use the bottle and your little one's abilities will change how much "weight" you place on the importance of the bottle's total weight.

In our review, the Platypus SoftBottle and Vapur Shades are bladder-style vessels that are the lightest at 0.1 lbs when empty. However, one of the most substantial options is the glass Lifefactory with Active Flip Cap. Its 1.1 lbs heft will only get heavier and more troublesome to carry when full of water, which could potentially increase its chance of getting dropped.

Ease of Use

The water bottle you decide to purchase should be easy to use. If it is challenging to operate, then your child will most likely not use it. As a result, it will not only take up space in the cupboard, but it will also be a wasteful purchase. While some little testers preferred bottles in their favorite colors, the products that were easy to drink from eventually won their hearts and the options they regularly reached out to use. Of the contenders, we consider the HydroFlask Kids Wide Mouth to be an easy-to-use option, as well as the Zulu Torque, which features a flip-top and straw that is easy to open and use for little hands. On the contrary, the button on the Contigo AUTOSEAL Trekker presented some issues for younger children. Also, we discovered that the Nalgene OTF is difficult to close, especially for preschools who may need assistance.

Ease of Cleaning

The level of convenience to properly clean your kid's water bottle is a big deal. If it is time-consuming or requires too many specialized tools, you will not use it as often, or you might feel tempted to skip washing altogether. Products with fewer parts, such as the Klean Kanteen Insulated Kid Classic, are preferable compared to options that need straw brushes to clean appropriately, like the Zulu Torque.

Bladder-style bottles, such as the Platypus SoftBottle and Vapur Shades are harder-to-clean options. For both contenders, the mouthpieces are narrow, and you'll need to prop the body open to allow air circulation in hopes of drying the inside fully, which can take time. Nonetheless, harder-to-use options will end up at the bottom of the drawer.

Most of the water bottles are straightforward to assemble and clean compared to sippy cups. In general, they have fewer parts and go together quickly. Most of the bottles require a bottle brush to clean suitably, but only a few need a straw brush, and we suggest parents have both on hand.

Hand-Washing Bottles:
We recommend handwashing any plastic parts in warm soapy water instead of putting them on the dishwasher's top rack. In our opinion, this minimizes plastic degradation and lessens the possibility of chemicals leaching into your drink. Also, all insulated containers MUST be washed by hand, as they have a double-walled structure that could potentially trap water, making the insulation ineffective and increasing the opportunity for microbial growth. Also, we suggest handwashing any stainless container with groovy paint to prevent peeling. However, if hand washing is not your jam, skip on the painted options, and select a plain uninsulated stainless contender as it is dishwasher-safe.

Safety Considerations

Leak-proof bottles can be potentially hazardous. From 1991 to 2010, approximately 45,000 injuries related to leak-proof cups and bottles were presented to the ER.

Here are some best practices, according to the American Academy of Pediatrics (AAP) and the ADA:
  • Children should only use bottles when stationary
  • Potentially avoid dental decay related to bottle use by only filling bottles with water, NEVER sweetened or carbonated drinks
  • To avoid potential issues with decay and dentition formation, limit water bottles for outings only
  • Parents should always provide a real cup when it is convenient

While it is wise to remember the ADA guidelines, we believe leak-proof bottles provide a valuable service for kids on the go as water bottles help keep children hydrated. They provide a service unmatched by a regular cup. With features designed with travel and convenience in mind, these bottles have earned a place in busy children's lives. Using standard cups at home, perhaps during mealtimes or water breaks, can offset some of the potential concerns with kids' water bottles.

Lead Concerns

We are aware that some parents have discovered lead in several stainless steel water bottles after performing tests on the bottles with at-home test kits. You should know that these results are not accurate of all stainless steel bottles as steel does not contain lead. The problem appears to stem from a small solder spot on the bottom of some bottles that can become exposed due to the destruction of the bottle's parts (loose bottoms, chipping paint). While manufacturers paint or cap the bottles' bottom to prevent this spot from being accessible, children can potentially be exposed to lead if the base is displaced or the paint chips. As a result of these concerns, we tested all contenders in our review for lead. None of the exposed parts of the bottles tested positive for lead, and we did not remove the bottom caps or paint to test underneath.

Safety Tip
We recommend that you take damaged bottles away from children and dispose of them properly as a precaution against lead exposure and other hazards. While we make every effort to choose durable products, all bottles can potentially become damaged over time through regular use. Parents should inspect all water bottle components during each cleaning for wear and tear, chewed parts, chipped paint, and other signs of damage. Some items, such as straws and mouthpieces, might be replaceable depending on the manufacturer, so you may want to check before recycling them.

Lead exposure causes multiple health issues for humans. Children are more susceptible to lead. After all, their bodies are still developing and because they often put their hands and other objects into their mouths. Exposure to lead usually happens due to contact with any lead sources, like some paints, older dishes and glass, contaminated soil and water, and other sources, including dust particles.

So, what are the dangers of lead exposure? According to the EPA, lead can affect almost every organ and system in your body. Lead is stored in bones and tissue, which causes continual exposure and potentially results in anemia, kidney problems, hearing problems, and slowed growth. It is a neurotoxin that can cause everything from headaches and memory loss to lower IQ levels and behavior problems.

The easiest way to check if your water bottles contain lead is to purchase a lead check kit. The test is easy to use and takes less than a minute for results. If the test results are positive, you should immediately dispose of the product.

Dirty Dust
Evidence shows that lead can be in dust particles from unknown sources or contaminated air from vehicles or industrial uses that travel through the air and settle on surfaces. It is a good idea to vacuum regularly and dust to reduce your children's potential exposure to lead. Removing your shoes after being outside can also help reduce the likelihood of lead contamination in your home.

Water Bottle Buying Guide

You may find yourself curious and questioning: How is a kid's water bottle different from a sippy cup? Why might you need one? Why consider a leak-proof water bottle in the first place when a cup will do? Read on to learn more.

Water bottles are helpful for on-the-go hydration. Running from school to soccer practice can build up a thirst, and finding a water source while running about, can be tricky. Alternatively, an easy-to-use and leak-proof water bottle can provide children with the freedom to move from place to place with a handy bottle. Many schools now request that little ones bring water bottles to class to prevent frequent trips to the water fountain and keep kids' brains working at peak levels. A water bottle for kids gives children the feeling of independence and encourages them to drink more water than they usually consume. This increased consumption helps children stay hydrated, which is a plus for the entire body. In our review, we will help you sort through the different types of bottles and their features, so you can decide which would work best for your family.

Why Get a Kid's Leak-Proof Bottle?

Typically, kid water bottles are for children over the age of three. You may wonder why a child this old would need a leak-proof container.

Regardless if you purchase a collapsible and lightweight water...
Regardless if you purchase a collapsible and lightweight water bottle or one that is sturdy and long-lasting, a crucial factor to consider is that your child approves, which may encourage drinking and hydration.

Using a leak-proof bottle is an easy way to get water in your child while keeping up with their busy schedules. Sending your little one out for a day of adventure with a full water bottle can improve their mood, ability to play, and overall, increase their level of hydration. With a bottle in hand, you don't need to worry about leaks, dehydration, or the need to find a water source while away from home.


  • Hydration — Continual access to water encourages children to stay hydrated for any adventure.

  • Transportability — Bottles are easy to transport and carry because they don't leak and are relatively narrow for smaller spaces. Some options can even attach to a pack or belt.

  • Convenience — Kids can drink whenever they want without looking for a water fountain, waiting to find a beverage, or making an expensive convenience store purchase.


Although there are many advantages to using a leak-proof water bottle, there are some disadvantages you should also know.

  • Potential Injury— Some bottles can have hard or stiff straw spouts that do not flex, and these designs can cause injuries if children fall with the spout in his or her mouth. While not as worrisome as a toddler learning to walk with a sippy cup in hand, it can still be a concern if children drink while in motion.

  • Increased Risk of Dental Decay— Consuming sugary or carbohydrate-rich beverages can increase the risk of dental decay. Limit water bottle use to water only, and this will help decrease this concern.

Kid Bottle Design

Compared to sippy cups, kid water bottles hold more liquid and feature a leak-proof valve or a closeable lid. The body is usually insulated and sometimes slightly contoured for easier gripping. The containers typically come in various colors and patterns, and some have recognizable characters on the side, while others offer abstract designs. Although none of our contenders feature a handle, some can connect to a backpack or stroller with a clip. Several bottles have lids or folding spouts to reduce the dirt and debris that can accumulate on the spout. Most of the bottles are easy to clean and assemble and disassemble with fewer parts than sippy cups.

Bottle Body

Kids' Water bottles are relatively tall, slim, and fit comfortably into cup holders, as well as little hands - even those with larger capacities over 12 ounces. They do not take up a lot of room in backpacks, and even the insulated varieties are relatively light and easy to transport. Most options require a bottle brush to clean, and some need a straw brush to clean the straws or mouthpieces.

Many water bottles on the market are of various materials, such as glass, stainless steel, plastic, and sometimes including silicone parts. Some bottles are primarily plastic with silicone parts, while others are stainless steel or glass with plastic lids. When it comes to materials, stainless steel is a more eco-healthy option than plastic, and it is easier to clean. But, the plastic bottles are lighter and less expensive. The material type can also impact how easy the bottles are to use and clean and how long they will potentially last. It is essential to understand each material's benefits and drawbacks before deciding which type of bottle to buy.

We encourage you to read more about plastics in our article, Are Plastics Safe for Bottles and Sippy Cups? to learn about the potential problems and concerns related to plastic use in bottles and cups for children. Issues concerning plastic in children's products are significant and worth reviewing before making a buying decision.

Children frequently refrain from using glass for obvious reasons (drops=breaks). However, glass contenders exist in the world of water bottles. We even tested one - the Lifefactory with Active Flip Cap. Glass is an inert substance that does not impart chemicals to its contents. It doesn't retain odors or colors from its contents, either. Unfortunately, it is breakable, which can be a problem when it tumbles around in a backpack or is tossed on the ground at a playground. While most glass bottles come with a silicone sleeve for protection from minor bumps and short drops, the sleeve does not provide 100% protection from breakage.

Stainless Steel

Food-grade stainless steel products are an excellent choice for active kids. Steel is durable, doesn't impart chemicals or odors into its contents, easy to clean, and is often insulated. If you're not convinced yet? It is also earth-friendly, eco-healthy, and recyclable.

We prefer stainless steel over other materials that can potentially leach chemicals into their contents. Given that steel is exceptionally durable and doesn't break, it also rivals glass options. Even though stainless steel is significantly heavier than plastic and insulated steel weighing more, we believe the tradeoff is worth it and that most children over the age of three will be able to hold and carry an insulated bottle with ease.

Steel products bring everything to the table in an economical package durable enough to last for years. Not only a healthier alternative to plastic but also eco-friendly and lasting. Klean Kanteen is one of the eco-friendliest bottles in our lineup, and their website has supportive information on the company's efforts to keep the Earth and your children healthy.


Plastic is a common kid water bottle material as it is budget-friendly, lightweight, and user-friendly. Plus, they often feature cool designs and colors that are eye-catching for little kids and parents. Parents might consider plastic for budget reasons, while children like the graphics and licensed characters often found on plastic bottles. Unfortunately, plastics have potential eco-health concerns that you'll want to consider seriously before making your final bottle buying decision.

Given the potential unhealthy properties of plastic, we feel it is essential that parents review the studies and history of this material. While BPA is no longer in use, that doesn't mean that plastic is always safe. Some studies indicate that many of the BPA-free plastics potentially leach chemicals into their contents; this means that some of the plastics in kid's water bottles may not be any safer than the BPA plastic they replaced.

A study from Environmental Health Perspectives states the following:

In some cases, BPA-free products released chemicals having more EA than did BPA-containing products.

Another study published in Environmental Health found that some plastics still potentially leach estrogenic chemicals .
Many unstressed and stressed PC-replacement-products made from acrylic, polystyrene, polyethersulfone, and Tritan™ resins leached chemicals with EA, including products made for use by babies. Exposure to various forms of UV radiation often increased the leaching of chemicals with EA.

Before you toss away your plastic containers, take a deep breath. The jury is still out on whether or not all plastics are culprits. However, we believe that exposure to potentially harmful chemicals should be limited or eliminated whenever possible. The studies we reviewed left us feeling that more research is needed and that parents should advance with caution. But, considering early study results, we recommend stainless steel over plastic when possible.

While the debate over plastic safety continues, we think it is wise to take plastic out of the equation by selecting stainless steel options. Even if plastic's lower price is enticing, we believe that steel is a healthier choice that saves money over time thanks to its durability and longevity.


Spouts, straws, sleeves, and valves of kids' water bottles are typically silicone. Most of the silicone is medical-grade, which is widely accepted to be safer than plastic.

The use of silicone keeps parts flexible and decreases the potential for injury. In fairness to plastic, it is only fair to mention that some preliminary studies show that silicone can break down when heated and can release small particles over time. As a result, we encourage you to hand wash silicone parts (or preferably all parts) to avoid breaking down the material.


Most of the bottles we reviewed have only a few parts and are easy to clean and assemble. A body, lid, and spout/straw are the typical components of kid's bottles, with most having three or fewer parts. Some bottles also include a leak-proof valve.


There are two basic types of spouts in kid's bottles, hard spouts and flexible straws. You can find some with a cup-like edge, which is typically just a short or modified hard spout.

Hard Spouts

Hard spouts are plastic and may or may not come with a silicone cover. They have little to no flexibility and can cause potential injury if children fall with spouts in their mouths. These hard spouts usually wear well over time and are often resistant to chewing and biting damage. While it is mouth-friendly, it is also stiff and unforgiving if a child falls with it in their mouth. If you have an aggressive chewer, a hard spout can be irresistible, but you should keep the dangers of this spout in mind when looking at potential bottles to buy and set some ground rules about not using the spouts when in motion.


Flexible straw spouts are less likely to cause injury than their hard spout counterparts and more closely align with the spout style preferred by the ADA. Straws help move the liquid to the back of the mouth, thereby skipping the teeth. As a result, it can potentially decrease the possibility of cavities, improve overall oral hygiene, and lead to less dental decay. The most significant disadvantage to straws is the time and energy required to clean them. Cleaning straws include disassembly, a special brush, and reassembly. Another problem occurs when straws become dislodged from their lids, rendering the bottles somewhat useless without adult help. While not a deal-breaker, it can be frustrating for children who drink and get nothing but air.

Cup-like Edge

Some of the products we consider have a cup-like edge, which provides a cup-like experience and prevents possible injuries that can occur with harder spouts. Also, it avoids the hassle of straw cleaning and maintenance. The only drawback of some of these bottles is the coordination and finger strength it takes to hold down the button that opens the valve while you tip the bottle and drink. With practice, most children can manage the feat, with older children experiencing more success.


Valves are the component of leak-proof bottles the prevent leaks. While some valves are more challenging to use than others, none of them are impossible. Unfortunately, you don't know how well a valve works until after you buy it. Reviewing the valve materials or the kind of valve isn't a good indicator of whether it will be easy to use or even prevent leaks. While the best valves may have things in common, it wasn't until we bought the kid water bottles and used them that we were able to determine which were easy to use and which were a struggle.

The American Dental Association (ADA) recommends that parents choose bottles and cups without leak-proof valves and limit sugary liquids to help avoid dental decay. For more information, please see the ADA article. While choosing a bottle without a leak-proof valve is easier with older children, as most kids over three can close lids to avoid leaks, leak-proof valves are still useful in kid's bottles.

How to Choose the Best Kid's Water Bottle

Selecting the right kids' water bottle doesn't need to be challenging. If you follow some basic tips, you'll be able to narrow down the options based on key considerations.

First, Choose a Body Material

Before choosing a water bottle, consider the many material options as each type holds pros and cons. We feel that material is an important decision, especially considering the potential health concerns of plastics and the benefits of insulation. Also, favoring one material over another can quickly eliminate competitors and narrow down the possibilities.

Without a doubt, our favorite kids' water bottles are stainless steel, as this material holds the most benefits. Not only is steel eco-friendly and healthy for humans, but it also does not leach chemicals or impart flavor. It is easy to clean, recyclable, and exceptionally durable, providing years of service to quench your child's thirst. Indeed, it will be around for a while. Plus, finding a stainless steel water bottle with insulation is not a difficult feat. While stainless steel is often more expensive and heftier than plastic, we think the extra expense and heft are minor given the health and environmental benefits, along with the durability and longevity.

Next, Pick a Spout

The second most important consideration is the water bottle's spout. Considering the injury potential and the ADA concerns related to hard spouts, we prefer a softer straw spout or a cup-like edge when possible. We also think kids' water bottles with a flexible straw spout are easier to use than many hard spouts. Lids that screw off can be challenging for younger users, but it helps that most options in our review have caps connected to the bottles, which decreases the chance of a lost lid. If your chosen spout is harder or of potential concern, we suggest encouraging your little ones to drink while staying still or, better yet, while sitting to avoid possible injuries.

Last, Choose Insulated or Non-Insulated

Water bottles with insulation have more potential than their non-insulated counterparts. Having cold water during soccer practice might be the ticket to feeling energized and refreshed. Plus, even if insulation isn't desired, it usually isn't a hindrance. The only downside of insulation is the extra weight, which is unlikely to cause difficulties for older kids but can be troublesome for younger children.


You may find yourself dizzy after surveying the various kids' water bottle options on the market, and finding one that meets your needs can be downright challenging. Thankfully, you can reap the benefits from our hard work as we dug through the details and completed hands-on testing of the top contenders to find the best.
