The Battle for the Best Disposable Diapers

Babies depend on their caregivers to provide comfort and security. Parents depend on diapers to keep babies dry and comfortable. You can depend on BabyGearLab for objective scientific reviews of diapers so you can quickly find the best product for your family.
Finding the best disposable diaper can be a chore and cost you more money than you'd like to think about. We've tested 24 diapers in our lab and in the real world to help you make a great buying choice for the right diaper for you and your baby no matter what is most important to you. We put each product through a series of tests designed to compare the diapers relative to each other. Our goal was to determine which diapers performed the best and if there was any difference between green diapers and popular brands like Pampers and Huggies.

Keep reading to find out what we learned from our tests, and how each diaper stacked up against the sometimes soggy competition.

Updated — Sept 2017
We've given two big box store brand diapers Best Value awards, the Kirkland and Babies R Us brand diapers. Neither is an eco-healthy diaper, and so many parents will prefer to pass on these two brands. But, both scored above average overall, while at attractively low prices. These aren't our favorite diapers, but deserve mention for those on a tight budget.

Best Overall Disposable Diaper

Nature Babycare

Editors' Choice Award

$0.35 each (in 124-pack)
(7% off)
at Amazon
See It

Great absorption
Few leaks
Good health and eco-friendliness
Not very cozy
Disappointing durability
Nature Babycare is great green diaper that is probably the closest thing to cloth diapering you'll find in a disposable diaper. This company and diaper are trying hard to set new environmental standards for diapers while keeping baby's health in mind. The best part? Not only is it green but it earned the highest score for absorption making it a top performing option as well. This diaper may not be the best choice for parents on a tight budget, however, if your wallet allows, you'd be hard pressed to find a better, eco-friendly disposable diaper anywhere.

Good absorption
Not as green as competition
Average leakage
Babyganics is a comfortable green diaper that lasts as long as you need it to between diaper changes with few complaints online about durability. This diaper impressed in its performance for absorption and it offers some features for eco-friendliness and baby's health. It is somewhat cheaper than Nature Babycare and may be a good choice for parents who favor comfort and durability over being as green as possible.

Comfy and Affordable

Kirkland Signature Supreme

Best Value Award

List Price
See It

Kirkland diapers are a Costco brand traditional diaper with some nods to health and a super high comfort score. This inexpensive option earned high scores for comfort and durability with super soft fabric and few online complaints about faulty tabs or falling apart. While this diaper is not a top performing option when it comes to absorption or preventing leaks, it will get the job done at a lower price than much of the competition with a similar price. We think this diaper is a potential choice for families on a budget with $0.07 price to performance ratio and a comfortable fit and feel.

Best Bang for the Buck

Babies R Us Supreme

Best Value Award

List Price

Babies R Us diapers are a store brand budget diaper made by Toys R Us. This diaper performed above average in tests for absorption and leakage with good scores for comfort and durability making it a contender for families with a limited budget. While it won't hit the mark for those looking for environmentally friendly or additional considerations for baby's health, it does get the diaper job done without breaking the bank and limited leaking.

Top Pick for Health

Seventh Generation Free & Clear

Top Pick Award

$0.32 each (in 155-pack)
at Amazon
See It

Nicer price
Great health score
Possible leaks
Not so comfortable
Seventh Generation is an economical green diaper for parents that want to be kind to the Earth and want more features with baby's health in mind. Seventh Generation is $0.10 cheaper per diaper than our top Editors' Choice option and has the highest score for health in this review. Combining that with good absorption, we think this diaper is a good choice for families who want a healthy disposable diaper that will get the job done without breaking the bank. If you are looking for the best choice for baby's health and skin, look no further than Seventh Generation, which is why it won a Top Pick for health.

Notable Non-Award Winners

While maybe not stand out award winners, some diapers are notable depending on what you are looking for or what their marketing promises, both good and bad.

Green and Healthy

Bambo Nature

$0.41 each (in 198-pack)
at Amazon
See It

Bambo Nature is a cool green diaper and a previous winner of an Editors' Choice award. This diaper earned a great score for health tying with only one other diaper out of 24. Bambo is chlorine, latex, perfume, and lotion free with an allergy certification and a full disclosure list on the company website, so you know what is in the diaper and what is going near baby's skin. This diaper is comfortable and eco-friendly with some cool manufacturing bragging rights other diapers can't claim. While Bambo is not the diaper for everyone, it does fit the bill for those looking for a healthy option with Earth-friendly manufacturing.

Notably Disappointing

The Honest Company Diapers

$0.58 each (in 34-pack)
at Amazon
See It

Honest diapers continue to disappoint in our testing. We are mentioning Honest diapers as notable for lower quality compared to competing green diapers in our current diaper review. In previous years, Honest earned slightly above average scores and now is scoring below average in our tests compared to past years and most other green diapers. Is this because other diapers have upped their quality or is it possible that mass production and a wider distribution has resulted in lower quality management or a change in diaper design to meet the demand? We aren't sure, but our test results indicate that there are better diapers on the market for your baby that cost less and have higher scores overall than Honest diapers.

Analysis and Test Results

If you're a new or expecting parent, let us level with you: your baby is going to make a lot of poo. Way more than you realize. This vast amount of poo will need immediate and continuous containment to avoid turning your life into a complete bio-hazard zone. Sure, you can try to distinguish your new baby's facial expression for signs of impending explosions so you can rush them to a nearby toilet, but we think it is easier to employ a diaper to do the dirty work (literally) for you.

If you are reading this, then we're going to assume that you're looking for help choosing a disposable diaper (before you flog yourself too much with your green-guilt whip, be aware that even the Sierra Club which takes a position, still admits that the decision is a tough one when trying to be more environmentally responsible). We're here to help by giving you the straight poop on all things diaper.

Feeling overwhelmed? Stop reading this and jump to our buying advice article, How to Choose the Best Disposable Diaper. We wrote it for you. It provides a helpful overview of the options that are out there, and what you should be considering before making your final decision.

The Great Diaper Questions

Figuring out which diaper to buy is a decision that many parents agonize over. We know, we've been through it (and we wish we knew then, what we know now). In this review we're going to attempt to take on our own Top 10 List of Great Diaper Questions and wrestle them to the ground:
  1. How many diapers does a baby go through in total?
  1. How much $ will I spend on diapers over time?
  1. What is the environmental impact of diapers?
  1. How do green diapers perform compared to traditional brands?
  1. What is inside diapers (and why should I care)?
  1. Which is better: Pampers or Huggies?
  1. Are big box private-label diapers just as good as brand name diapers?
  1. What's the best green diaper?
  1. Which is best: Cloth vs. Disposable diapers?
  1. Which diaper should I buy?

OK, in full disclosure, we're not going to take on #2, Cloth versus Disposable, not here anyway. Instead, we're going to refer you to our complete analysis of that question in a separate article, Cloth Diapers vs. Disposables: How and what to choose?. You can review all things cloth diaper in our review titled, The Search for the Best Cloth Diapers. But, we are going to wrestle those other nine questions to the ground right here and now. We promise.

We tested over 24 disposable diapers in our big diaper show down.

Putting 24 Top Diapers to the Test

We tested 24 diapers giving each a chance to vie for our top awards. We used a combination of hands-on testing (day-to-day diaper use on real baby bottoms, carefully monitored and annotated), lab testing, and research to compile facts and observations that would allow us to rate each diaper fairly on performance metrics relative to their competition.

We made our selections of which diapers to test carefully, to ensure a complete picture of diaper performance for our readers. We've included a variety of green diapers pitted head-to-head against traditional options. We included Pampers and Huggies offerings, but we also included private label brands from Costco, Target, Walmart, and Babies R Us to see how they would fair when compared side-by-side with the brand name diapers.

Babies go through approximately 6 000 diapers during their diaper wearing years!
Babies go through approximately 6,000 diapers during their diaper wearing years!

Wait! How many diapers are they going to need?

In the first year, your tiny mini me is going to go through about 2,500 diapers. If that number is daunting and hard to grasp, it breaks down to something like 10-12 diapers a day on average for the first few months, then about 6 per day for the rest of the first year. In year two, you can expect that pace to slow to about 3-4 per day, and that pace may continue into year three when potty training starts to take hold. Even after potty training, they'll probably still use one overnight diaper per day for another year or two.

Estimated diaper usage over time is shown to be a total of nearly 6 000 diapers in the chart above. Your mileage will vary since babies grow at differing rates and the total depends on potty training timing  and overnight use after potty training. (Click on the chart to enlarge)

Add it all up, and your precious bundle of joy is going to amass a mountain of roughly 6,000 dirty diapers. That's a lot of diapers to put in the landfill, which is why a growing number (but still a minority) of Moms consider green-diapers or choose cloth diapers.

So, what is all that going to cost me?

If you are price conscious when buying diapers, here is the breakdown: let's assume our estimate of using approximately 6,000 diapers over your baby's lifetime is correct. Price per diaper varies depending on the size of the diaper; the bigger the diaper, the higher the price. Also, when considering price, keep in mind that they'll use a lot more size 3 & 4 diapers than the smaller sizes. We recommend doing your price-comparison using Size 3 as a standard, because it will give you a more realistic cost average since some manufacturers may deeply discount small sizes to get you hooked, only to charge more later.

If you buy a name brand diaper like Pampers Swaddlers, you'll be spending approximately $0.33/diaper on average. If you buy Kirkland, you will spend about $0.16/diaper. If you buy a quality green diaper like Seventh Generation, you will be spending about $0.30/diaper; or for the Nature Babycare, it's about $0.37.

What does that come to for the four years you will be using diapers?

Kirkland will cost approximately $960 for 4 years and $20 a month
Seventh Generation will cost approximately $1,800 for 4 years and $37.50 a month
Nature Babycare will cost approximately $2,220 for 4 years and $46.25 a month

Keep in mind that these prices are high; if you sign up for a subscription program like Amazon offers, you will get 20% lower prices on most of the brands.

Nature Babycare diapers earned the highest overall score in the review with the top score for absorption.
Kirkland diapers are a comfortable durable option with a reasonable price point.

Is It Worth Paying a Premium for the Best Diaper?

The step-up from Seventh Generation, a great performing green diaper, to the best performing Nature BabyCare diaper, is about $11 more per month over the four years your baby will wear diapers. But the price jump from a cheaper diaper like the Kirkland is closer to $26. You might be wondering if it is worth the extra money to buy the better diaper.

While we feel strongly that Nature Babycare is the best diaper we tested, it does cost about $0.07 more per diaper than Seventh Generation. It costs $0.17 per diaper more than Kirkland. That is about $25 more a month to buy Nature Babycare over Kirkland. The numbers decrease somewhat if you consider Seventh Generation. So is it worth it? Let's compare the scores.
  • Kirkland (below left), 6 absorption, 3 health, 1 eco, 58 overall
  • Seventh Generation (below right), 8 absorption, 8 health, 6 eco, 70 overall
  • Nature Babycare, 10 absorption, 7 health, 8 eco, 76 overall

Absorption tests on the Kirkland diapers indicated it absorbs liquids quickly so baby can stay drier.
Seventh Generation diapers had only a small amount of moisture transfer to the test paper.
You can see almost no moisture transfer onto the test paper for the Nature Babycare absorption test. This translates to a drier baby which could mean less skin irritation  less diaper rash  and a happier baby.

The difference between Kirkland and Seventh Generation is significant. Seventh Generation offers a good balance between cost and performance for most families. This diaper scored well in most metrics, better than Kirkland, with the bonus of providing some Health and Eco-friendly advantages. For $5 more per month, we feel the benefits are great if your budget can afford it. But, if you just want the best for your baby, even if it means spending a bit more, then Nature Babycare is our pick. However, we also understand that despite what you want sometimes it comes down to what you can afford. Both the Kirkland and Babies R Us brands offer a better than average performing diaper at a lower than average price point.

Environmental Impacts

Disposable diapers have a significant environmental impact. When you consider that an estimated 90% of US babies use disposable diapers, and there are 4 million babies born each year, each going through 6,000 diapers, the environmental impact of disposable diapers going into landfills is very large.

Here's some information we believe to be factual:
  • The Environmental Protection Agency reports that about 20 billion disposable baby diapers end up in landfills every year, a shockingly large amount, yet we feel that might be low (our estimate is nearly 22 billion). This creates approximately 3 billion pounds of US landfill waste each year.
  • Traditional disposable diapers do not degrade well in landfills due to plastic materials used and lack of exposure to air (which hampers biodegradation)
  • Some % of disposed of diapers contain feces (the right thing to do is flush feces before throwing away the diaper) which present a bio-hazard risk to landfills and may seep into ground water.

Who Knew? Now YOU Do!

It is this last bullet that may be the deciding factor in the "which is greener" debate between cloth diapers and disposables. If you use modern cloth diapers, most likely with a flushable liner, you are most likely flushing your baby's poo. Flushing poo is far less damaging to the environment than throwing it away (and creating a biohazard risk in landfills). But you can, and should, flush poo from disposable diapers to prevent this environmental impact.

How do green diapers perform compared to traditional?

Choosing between using a traditional or green diaper has not been easy. And, many people have assumptions about green diaper performance which we found to be false: green diapers outperformed traditional diapers on absorbency and most other metrics.

You can find the full details of our analysis, based on test data and findings from our comprehensive review of 24 top diapers, here:
Diapers are constructed in three layers  an inner layer that sits against baby's skin is designed to be soft  stay relatively dry  and wick away moisture into the core. The absorbent core is designed to pull moisture in and trap it to keep wetness away from baby to avoid rashes. The outer layer is waterproof to prevent leaks.

The absorbent core is designed to pull moisture in and trap it to keep wetness away from baby to avoid rashes. The outer layer is waterproof to prevent leaks.

What's in My Baby's Diaper?

All disposable diapers in our test look a lot alike. They each contain an absorbent core, an inner layer designed to keep baby dry, and a waterproof outer layer. Yet each diaper may contain vastly different materials than another, and some of these ingredients may be considered risky or potentially toxic. To help address parents concerns about the materials inside disposable diapers, and what risk they may or may not pose baby, we've created a detailed article entitled, What Is Inside Those Disposable Diapers? This article is an overview of each potentially hazardous material that may be in some diapers, what the problem is with that material, and what we recommend you do.

The secret sauce inside the absorbent core layer of every disposable diapers is a synthetic material called Super Absorbent Polymer (SAP). It is magic in it's ability to suck up to 300 times it's weight in water  which is why it is so widely used. Researchers are now making a plant-based SAP in labs  but as far as we can tell  every diaper in our review likely uses the more time-tested petroleum-based SAP.

Absorbency Is The Performance Standard for Diapers

As we note in our How We Tested Disposable Diapers article, we believe that absorbency is the most critical performance criteria for diapers. Given how much emphasis manufacturers give to claiming top absorbency, we think they must feel the same way. We performed a combination of hands-on testing and in-house lab tests to wring out the real-world absorbency performance of each diaper. What we found was a huge difference in absorbency, even more so than in previous years.

You can see almost no moisture transfer onto the test paper for the Nature Babycare absorption test. This translates to a drier baby which could mean less skin irritation  less diaper rash  and a happier baby.
The poof has the lowest score for absorption with an excessive amount of urine captured on the test paper  implying that the core of the diaper struggled to lock moisture away from baby's bottom.
The photos above include the top tanked diaper for absorption, Nature Babycare with a score of 10 (left), and the lowest scoring diaper for absorption, Poof with a 1 (right).

Every year we've tested diapers, we've been impressed with the fact that green diapers have delivered top scores for absorbency. This year was no exception. The top 5 diapers in absorbency were all green diapers! All had scores of 8 or over. The top traditional diapers, Babies R Us and Parent's Choice, both scored 7s.

While certainly not the worst in the group  the Swaddlers absorption test results indicate that not all of the moisture is locked in the core of the diaper and some will stay in contact with baby's skin.
We didn't like that the Snug & Dry performed poorly in our tests for absorption with more wetness transfer than the higher scoring competition.

Which Is Better: Pampers or Huggies?

For the first time in our 3 years of testing, the winner here was a tie. We tested Pampers Swaddlers, Pampers Swaddlers Sensitive, Pampers Baby Dry, Huggies Little Snugglers, and Huggies Snug & Dry. Both Pampers Swaddler varieties earned an overall score of 46 and the Baby Dry style earned a 45. Huggies Little Snugglers earned a 46 and Snug & Dry a 48.

If you are trying to decide between Pampers and Huggies, we recommend you go with Pampers. Both brands have similar scores for absorbency and similar prices, but Pampers offers a little more for baby health. This makes it the winner in our book. However, we advise that you look outside both of these well-known brands at either our Top Pick, Seventh Generation, or our Editors' Choice award winner.

Huggies Snug & Dry is a popular diaper with a good leakage score but poor absorption.
Pampers Swaddlers is a soft and cozy diaper that almost feels like cloth.
Pampers Swaddlers Sensitive is a soft diaper with wetness indicator.
The Huggies Little Snugglers are comfortable and cute with Disney characters and a useful wetness indicator.
Walmart White Cloud diaper is budget friendly with a better than average performance for absorption.
The Walmart Parent's Choice diaper has a cute pattern (contains dyes) and a cheaper price.
Babies R Us store brand diapers offer fairly good absorption and leak protection but provide very little for the health or environmentally conscious.
Kirkland diapers are a comfortable durable option with a reasonable price point.

Are Big-box Private Label Diapers the Same as Pampers and Huggies


We tested private brand diapers from the four major big box retailers: Target, Walmart, Costco, and Babies R Us. In the end, we concluded that each was different from other name-brand diapers (Pampers and Huggies) as well as each other in both features and performance. In general, all varieties placed fairly low in the group with only Kirkland, Babies R Us, and Walmart's Parent's Choice and White Cloud breaking the top 12. All Pampers and Huggies varieties scored in the lower half. These results mean the store brand diapers performed better than the popular brands and will likely cost you less as well.
