Kirkland Diapers Review (What Parents Think)

Are you using the Costco/Kirkland brand of diapers? Or thinking about switching? My family has used these diapers (and many other brands over the years). In this article, we’ll talk about Kirkland diapers, I’ll share our experience with the diapers, as well as what others seems to be saying based upon their experience.

Who makes Kirkland diapers?

This is a great question! Kirkland sources their diapers from Kimberly Clark, who also happens to be the manufacturer for another diaper that you are probably familiar with (Huggies). It is no wonder that people are often wondering whether Kirkland diapers and Huggies diapers are the same.

I don’t have access to any older versions of Huggies diapers, but there are other bloggers out there who say that Kirkland diapers are an older version of a Huggies diaper and if you could compare them, you’d see that they are the same.

Here’s a roundup of what parents are saying about Costco diapers.

Kirkland Diapers Review: We Really Liked Them!

In my personal experience, Costco diapers are pretty awesome. I used them with each of my three children (two boys and a girl). I found them to be of high quality, and very effective in keeping the pee where it should be. I was pleased with the quality of the material, and while the diapers were affordable (meaning almost always cheaper (on a per diaper basis) than I could find diapers on the shelf at the regular grocery store), I didn’t feel that the diapers were “cheap” feeling.

I have purchased the generic brand of diapers from Winco, Walmart, Safeway, and other grocery stores. The other generic diapers felt “hard” and scratchy, and smelled like chemicals. My kids seemed to get more diaper rashes with generic brands as well. Further, they tended to rip, and didn’t hold all that much of the #1 or the #2.

My overall recommendation for Costco/Kirkland diapers is a solid 4.5 out of 5. (We used 1000s of Kirkland wipes as well). But see below for what others have to say.

Other Costco Diaper Reviews were overwhelmingly positive.

I’ve reviewed a ton of products. It is seldom that I see such positive reviews about a product, period.

Having tried the cheap-o diapers (along with Pampers, Huggies, and others) I was not surprised then, to see the following reviews about this Kirkland product:

  • diapers absorb better than pampers
  • hold much more than pampers
  • great price for a giant box
  • great fit
  • no leaks

  • hold up well
  • super chubby legs and still fit great
  • very affordable
  • no scent at all
  • repeat buy
  • baby likes them fine

  • good quality, without being paper thin
  • run true to size
  • never irritated sensitive skin
  • very functional
  • do the job well
  • work really well

  • hold up really good
  • comparable to Huggies (which is apparently a good thing?)
  • awesome price tag
  • totally worth it
  • best value
  • perfect because they stretch
  • love the yellow/blue line feature (when diaper is wet)

  • contoured nicely and very absorbent
  • love the stretchy waistband around the back
  • no harsh smell
  • not a droopy diaper
  • no more blow-outs
  • baby can go 12 hours overnight without leaks
  • love that Costco does sales with free shipping on diapers
  • happy with this product

Truly, there are hundreds of positive reviews from raving fans of these diapers.

However, not every user of Costco diapers loved them.

Here’s what the haters had to say:

  • gave daughter a terrible rash
  • fine, cost effective, but not as soft as wanted
  • not absorbent at all
  • Absorbed pee very well but easily defeated by poop monster little boy
  • size was really too big for the child so pee leaked a lot

  • just okay
  • too stiff
  • comparable to Huggies (which is apparently something negative?)
  • not cute enough
  • leaky
  • design is “crappy” (as soon as you pop off the diaper it folds in on itself getting poop everywhere)
  • fails to hold in massive blowouts

  • elastic on the legs wasn’t stretchy enough
  • when the child pees, the diaper REALLY smells like pee
  • annoyances with the recent changes to design (don’t fit the same)
  • loved one size but hated next size up (didn’t fit well)
  • recent design changes to the wings/tabs are bad, the closure is not smaller, skinnier and weaker, and the tabs rub on baby’s skin

Bad experiences with diapers make you want to rush your child through the process of using the potty and learning to wipe!

Kirkland Diapers Sizing

Here’s how the various sizes are divided up:

Size 1: up to 14lbs

Size 2: 12-18lbs

Size 3: 16-28 lbs

Size 4: 22-37lbs

Size 5: 27 lbs and up

Size 6: 35lbs and up

Are Costco Diapers Cheaper? [Cost comparisons]

The cost of the “giant” box of diapers is generally about $35-$44 dollars, though the price fluctuates some between the various sizes. However, if you are purchasing these diapers through Costco, remember that the membership fee of at least $60 per year is required, and you need to factor that extra cost into the price. If you are not a Costco member, you can order from without being a member if you pay a small transaction fee (a few dollars).

Here’s what the diapers cost from (as of the date of publishing this post):

Size 1: $30 for 192 diapers (0.15/diaper)

Size 2: $30 for 174 diapers (0.17/diaper)

Size 3: $36 for 198 diapers (0.18/diaper)

Size 4: $36 for 180 diapers (0.20/diaper)

Size 5: $36 for 150 diapers (0.24/diaper)

Size 6: $36 for 120 diapers (0.30/diaper)

Across the board it seems like the larger the diaper, the more each diaper costs. Makes sense. Which is yet another reason why parents can’t wait for babies to get big enough to stop wearing diapers.

You can actually get access to these diapers without a Costco membership. I have seen them for sale on,, and on eBay. The prices vary (from platform to platform and from day to day), but you’ll see them for sale for similar prices. Again, remember to factor in additional costs in your per diaper breakdown, such as shipping or taxes.

In most cases, the price is fairly competitive with stores around the internet. But if you don’t have a Costco membership, paying the same price and getting free shipping from Amazon may actually be a better deal than paying for a Costco membership. (In addition to spending money on gas to drive to Costco, and then also buying all of the wonderful things that there are to be found within the four walls of a Costco).

How does pricing compare to Pampers and Huggies?

I did a bunch of hunting around Amazon to get an idea of the costs per diaper. What I found is that it varied widely. I think if you look hard enough, you can probably find diapers on sale SOMEWHERE, and find a better deal than what I have listed here for Pampers and Huggies, though you might not find the deal in your local supermarket on your way home after work.

In any case, it seems overall like it is possible to get a better per diaper deal with Costco diapers, if you aren’t factoring in the membership fees or shipping costs on top of the basic price for the diaper. Obviously if you are buying the Costco membership just to get deals on diapers, you’ll have to factor in that cost.

Kirkland Diapers vs Huggies

As discussed above, Huggies and Kirkland diapers are made by the same manufacturer. You’d assume that since Kirkland diapers are an older version of the current Huggies diaper on the market, that the current version of Huggies will be better, right?


Here’s the thing. You can see that every family has a different experience with a specific diaper, often because of the individual characteristics of the child and their own preferences. For example, so people report that the elastic around the legs was too loose and didn’t hold in all of the wet or chunky, while others complained that it was too tight and didn’t fit right. Some people like the materials while others did not.

For my family, we actually preferred the Kirkland diapers over the Huggies diapers. The reason? The leg holes never fit quite right for my children. They seemed to be cut just a little too large and nothing I could do with tightening the straps at waist level would ever improve the fit. As such, my kids were ALWAYS struggling with leakage in Huggies diapers. This led to an uncomfortable child, and made our struggles with diaper change tantrums worse.

Does this mean that Huggies is a bad diaper? Nope. It just didn’t work for us. Ultimately, you’ll have to try out all the diapers and see what performs the best for you.
