The Skinny

The Pura Kiki Stainless sippy cup is one you can feel good about using with your baby, no question. This plastic-free sippy cup stands out on all the points that really matter: baby's health, eco-friendliness, ease of use, and ease of cleaning. It has great versatility; by simply swapping from baby nipple to the firmer blue silicone Pura Kiki XL Sipper Spout, baby bottle converts to a transition or toddler sippy in seconds. This savings in both cost and extra effort is a big deal in our book. Worth noting, however, that there is a hidden cost in that we feel the optional $7 Pura Kiki Short Silicone Sleeve is a must to help little hands grip the bottle, which consequentially makes it the most expensive sippy in our tests. Despite this, we feel that this thoughtful, healthy, and durable bottle will last through many stages and for many years through multiple children, so it is indeed very worth the investment.

Update — November 2016
Pura has mad a few changes to their bottles. Read more below to learn about the differences.

Old Pura Kiki vs New Pura Kiki

Pura has changed their Kiki line. All of the bottles are still made with medical grade silicone and stainless steel, keeping them 100% plastic free, but they are now unpainted, leaving plain stainless steel as the only color option for the bottle itself. This change makes all components of the bottle dishwasher safe and will prevent any issues with chipping paint. The silicone sleeve that we think is a necessity now only wraps around the sides of the bottle, leaving the bottom exposed to the possibility of dings and dents. The price of the 5 oz bottle has gone up to $15.50 (not including the XL sippy spout), but the recommended silicone sleeve is now included. Below you can see the new Pura Kiki 5oz Infant Bottle with Sleeve (left, included with a nipple only), the new Pura Kiki XL Sipper Spout (center, included only with the 11oz Toddler Bottle with Sleeve), and the older version (right, pictured with the old blue XL Sipper Spout).

Hands on Gear Review

The Pura Kiki Stainless Sippy offers the best in eco-health. It is 100% free of all plastic, but still weighs significantly less than glass competitors, and is mad completely with anti-bacterial #304 stainless steel (the same steel used in milk pasteurization), and is dishwasher safe. The non-insulated sippy comes in 2 size options; a 5 oz Pura Kiki Infant for which the Pura Kiki XL Sipper Spout must be purchased separately and an 11 oz sippy cup size that includes the XL Sipper Spout. For a transition sippy we like the 5 oz bottle option, as babies might have difficulty with the larger size and weight. The Pura bottle can be converted to a sippy simply by changing the mouthpiece to a firmer, blue (now clear) XL silicone sipper spout. If your little one used this as a bottle, the transition becomes inexpensive and much easier for baby's adjustment. Easy to use, clean, and assemble, you'll be hard-pressed to find a bottle as simple and health-savvy as the Pura.

Pura has addressed a real issue in terms of cost for its consumers. Previously, if one was to buy the 5oz Infant Kiki ($14), a set of 2 XL Sipper Spouts ($5.50), and a Short Silicone Sleeve ($7), the total cost would come to $23.25 to $25.50 (depending upon if you factor in the cost of one versus two XL sipper spouts). This was a pricey situation. With Pura's updated inclusion of a shorter silicone sleeve, their 5oz bottle ($15.50) plus XL sipper spout comes to a total of $17.75 to $20, again, depending upon if one of two sipper spouts is factored into the price. With this change, Pura is at least meeting closer to where the higher-end competition is priced.

There is so much to like about the Pura Kiki it is hard to know where to start. First, there is NO PLASTIC, no really, none. The stainless steel body and silicone spout is a refreshing change from all the plastic out there! The Pura's modern, sleek design is utilitarian, attractive, and safe. Plus, the slim silhouette will fit in just about any cup holder. The bottle has a wide opening and an internal surfaces that have been electropolished for easy cleaning.

The Pura scored very well in our hands-on testing, scoring well in all metrics and taking home the top honors for high score overall. We felt it washed "cleaner" than the glass and plastic cups we tested, leaving no residue or film on the inside surfaces. The stainless steel construction also meant no potential for leaching chemicals or heavy metals, and no risk of breaking glass or related injuries.

The body and neck pieces are fabricated from #304 stainless steel, which has anti-bacterial properties that make it ideal for items that hold consumables. This grade of stainless steel is thick and high quality, making it less prone to dents, and it more resistant to corrosion and staining.

This cup had great leak scores doing slightly better in the upside down test than the side spill. The spout can retain a few drops of liquid after drinking and this was "spilled" when the cup was tipped, but there was no significant leaking to speak of in either test. The cup also comes with a soft silicone travel cap. It can be slightly tricky to get the cap on exactly right, but once in place, it serves its purpose. the cap is not necessary to prevent leaks, but it was a nice addition for doubling the leak resistance and keeping the spout cleaner.

You can purchase the bottle in natural stainless steel or a variety of colors that are painted overtop. We suggest using the natural stainless with the optional silicone sleeve rather to improve grip properties. We prefer the clean simplicity of natural stainless, combined with the cushy comfort of the silicone sleeve, over paint that may chip over time.

We also liked that this cup is easy to clean requiring nothing more than a standard bottle brush to reach the bottom. The cup has three parts and comes apart easily. The spout can be cleaned by hand and needs little massaging to clean it properly. We recommend hand washing but, given that it is top-rack dishwasher safe and contains no plastic you could stick the body in the dishwasher and clean the spout by hand.

In addition, this cup's spout was so easy to drink out of, we gave it some points for adhering closer to the American Dental Association desire of a no valve cup. Theoretically, we feel this could lead to better oral hygiene.


While there is much to like about the Pura Kiki, the primary drawback is its hefty price. The 5oz system costs around $13.99 and the 11oz about $15.99. Unlike the glass cup and sleeve, Lifefactory Glass Bottle set up, this price does not include the silicone sleeve which costs extra. We feel the combined price for the 5 oz system with the sleeve is the price you should consider, which makes it the most expensive bottle system in our review. However, we feel the price is worth it given the longevity of the product, the interchangeable mouthpieces, the durability of stainless steel, and the eco-health value.

Another cost to consider is that the 5oz version only includes a soft spout nipple. So, when transitioning to a sippy, you will need to purchase either the firmer blue Pura Kiki XL Sipper Spout or the thinner Pura Kiki Silicone Soft Spout separately.

The stainless steel construction gives these bottles a modern appearance, but we feel that the silicone sleeve addition is a must-have. Not only does it provide a more comfortable in-hand feel, but it helps the bottle retain a more neutral temperature to the touch. Although the bottles shouldn't be exposed to temperatures higher than 50C (see our article, Best Practices For Handling Breast Milk), the bottle could get pretty warm to the touch if left in a car or cold if kept in the fridge. Always, always check the temperature of the bottle's contents before handing it off to your child.

We found the silicone sleeve was extremely difficult to get on, and once you get it on you will want to leave it on to avoid an emotional break down; Pura describes the sleeve as "semi-permanent". The company notes that the sleeve is "designed to fit tightly so that it will stay on the bottle through repeated dishwashing." However, we preferred the Lifefactory Glass bottle's silicone sleeve which: a) comes standard with the bottle and b) is much easier to take on/off.

The photos above show the Pura with and without a silicone sleeve.

The bottle does leak slightly when tipped over, but we think this is just the remains from the last sip trapped in the spout. It doesn't leak at all if the silicone cap is on it, however, unlike the Thermos Foogo Phase 3 Insulated, the lid is a separate item that may not be handy when you need it most. Depending on the bottle contents this might be a deal breaker or a minor annoyance.

We also didn't like the volume measurements being on the inside of the bottle. The 5 oz bottle only shows the 2 oz and 3 oz marks, and the instruction manual shows that 4 oz would be at the neck of the bottle and 5 oz should be about where the thread for the top begins. They claim those measures are "within 10%" accuracy. So in order to tell how much has been consumed you will have to take the lid off to look inside. However, this may just be a necessary evil given the non-see-thru properties of stainless steel. It is also less of a concern as children get older and parents stop monitoring fluid or feeding intake as closely.

Things just keep getting better as this company has recently released their Pura Kiki 9oz Insulated Infant Bottle and Pura Kiki 9oz Insulated Toddler Sippy Bottle for $23 each which keeps liquids warm or cool for up to 6 hours. These are basically the same except for either a nipple or spout that is included.

Accessories available for this sippy are the same ones that are compatible with any Pura Kiki bottle. They include:


Overall, we had a great experience with this sippy and it has become the preferred sippy for our editors. The co-health benefits are hard to beat and the simple design and thoughtful attention to detail make it a cup babies love as much as their parents. We gave this sippy our Editors' Choice award, our most coveted title. While pricier than the other cups or systems we tested, we feel both it's durability and ability to convert from bottle to transition to sippy to sport bottle makes this a great long-term investment, which might save you money over time.
