The Best Swim Diapers on Amazon, According to Hyperenthusiastic Reviewers

Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ’em) products and single out the most convincing. While we’ve covered the baby-rearing essentials (in Google spreadsheet form, no less), highly rated baby tubs, and sun-protecting gear for babies, here we dive into the best swim diapers on Amazon. Note that reviews have been edited for length and clarity.)

Best reusable swim diaper

I Play Snap Reusable Absorbent Swimsuit Diaper
$13 at Amazon

“My son is a pool pooper, unfortunately. These are the first swim bottoms that actually contain the mess and give us time to get out of the pool before it spills out. They look like little bloomers, which is pretty cute and funny on him. They are also easier to put on than a lot of baby swim bottoms. I’m ordering more.”

Best adjustable, reusable swim diaper

Beau & Belle Littles Nageuret Reusable Swim Diaper
$15 at Amazon

“I am SO HAPPY that I made the choice to go with this one. The first use, at the public pool, after about an hour of playing in the water, running in and out of it, and even swimming with mommy in the deep pool, my 18-month-old made a stink. A huge one. I took off the Beau & Belle Littles diaper and got a handful … while gross I was AMAZED and THRILLED that there was no leakage!”

Best disposable swim diaper

Huggies Little Swimmers Disposable Swim Diapers
$14 at Amazon

“These are great for my 2-year-old. Unfortunately, he enjoys swimming so much he doesn’t want to stop to poop or kindly inform us when he’s done it, so we have had to find out several minutes later when we smell it. Fortunately, this diaper has kept everything ‘in,’ so to speak, a number of times.”

Best reusable swim diaper multipack

Wegreeco Baby & Toddler Snap One Size Reusable Baby Swim Diaper 3-Pack
$14 at Amazon

“We were very happy with the reusable swim diapers! I’m a disposable-diaper mom all the way, but these are making me think differently. We’re still in the ‘newborn runny poop’ phase, but these diapers held that in. Which I’m so grateful for since she’s only 2 months, and she slept the whole time we were at the pool … On me. 😂 Needless to say, I wasn’t covered in urine or poo! Thank you!”

Best reusable swim diaper with side ruffles

From $13 at Amazon

“Love this little swim diaper. It fits nice and snugly around my baby’s waist and legs without causing any chafing or discomfort. I found these to be more comfortable and effective than disposables. If you’ve ever owned a swim diaper without snaps on the side, you’re going to kick yourself for not discovering these sooner. The last thing you want to do is to try to pull a wet, poopy diaper off your small child on a sandy beach without getting poop everywhere.”

Best reusable swim diaper with side snaps

I Play Baby & Toddler Snap Reusable Absorbent Swim Diaper
$12 at Amazon

“I have a small child, and disposable swim diapers do not come in sizes small enough to fit her! What was I supposed to do? We WERE going to take her swimming! My sister loaned me her reusable iPlay swim diaper and I fell in love! I had to purchase my own! This swim diaper is easy to use. The snaps on the side make it easy to put on and take off. The lining makes it lightly absorbent, too! Most swim diapers do nothing for the urine, just contain poop. This swim diaper I was able to put on my daughter before heading to the pool, it contained the urine while in her car seat and contained the poop perfectly!”

Best reusable swim diaper with Velcro and tie

Kushies Swim Diaper
$12 at Amazon

“We’ve used these swim diapers for two years now and love them. They’re easy to get on, and can be put on like a diaper, which is good for the younger babies. Also, we’ve never had a leak or lost a diaper with these. The Velcro plus tie is a nice feature. The elastic around the legs is fantastic and just tight enough. We’ve tried other swimmers that are sooo tight, they leave red marks, this swim diaper doesn’t and still holds in the important stuff. I will only use Kushies for swim time!”

Best reusable swim diaper with Velcro

Bummis Swimmi Cloth Diapers
$17 at Amazon

“We used the Bummis this entire summer and I was very pleased with their performance. First off, Bummis don’t squeeze chubby baby thighs. Also, Bummis held in what would be literally an equivalent of a bucket of diarrhea. Gross, I know … but it happens. We were on a beach vacation when our 2-year-old told us ‘poop in the pants,’ we checked and the Bummis were completely full. We rinsed them thoroughly with a hose and dish soap outside before putting the swim diaper in a hot-water wash (it took four washes because it was really stinky). And just laid them out to dry in the sun. Hooray for Bummis!”

Best swim trunks with built-in swim diaper

I Play Baby & Toddler Colorblock Trunks With Built-In Swim Diaper
$20 at Amazon

“As much as my little cutie looks ERRMERGERD so cute in his swim diaper, now that he is a little older, I wanted to get him something a little more ‘like daddy’ and a little less ‘Euro look.’ This is PERFECT. The swim diaper is sewn directly into the swim trunks; you would never know it’s there, and he can toddle around with the big kids! Obviously, it won’t hold pee all day, but one or two I have noticed won’t soak through (just be sure to rinse it after!!).”

Best two-piece swimsuit with built-in swim diaper

I Play. Baby & Toddler Girls’ Tankini Set With Built-in Absorbent Swim Diaper
From $21 at Amazon

“This is an incredibly well-made bathing suit. Love the built-in swim diaper. You might be thinking, Should I spend this much on a bathing suit for a baby? Yes, you should, if you’re planning to take her into the water with any regularity. Check out the price of swim diapers and do the math. You WILL end up saving yourself money by getting this bathing suit.”
