Perfect Swim Diaper – Just What I Needed!
As a new mom, I’ve been searching for a reliable, eco-friendly swim diaper, and I’m so glad I found this one! The Baby Swim Reusable, Washable & Adjustable Diaper is exactly what I was looking for. It’s not only adorable in design but also incredibly functional. The adjustable snaps make it easy to get the perfect fit as my baby grows, and it stays in place during swim time without any leaks.I love that it’s reusable—saving money and reducing waste at the same time. It washes well, dries quickly, and feels soft on my baby’s skin. Highly recommend this to any parent looking for a swim diaper that’s effective, durable, and gentle. Total game-changer for pool days!

Adjustable to keep a perfect fit as your baby grows!
My toddler is turning 18 months and used these since she was 3 months old. They are great! We (luckily) cannot speak to their ability to hold in solids (which is actually one reason I was waiting on the review so long) but given how adjustable they are I definitely feel more secure having our baby in these over the Pampers ones we also have used which never fit her just right.Also, since I was one of the many people who at first thought pee coming through swim diapers meant a poor fit, I want to add that these and most other swim diapers are advertised as being meant to hold in solid waste (if they held in liquids, the diapers would get all poofy!).

Quick delivery
This will be a gift so can’t speak to substantiating any claims but they were received quickly, well packed and are very cute.

Cute and Works Well, But a Bit Tricky to Put On
These swim diapers are super cute and do the job well, no leaks and they fit snugly once they’re on. I love that they’re reusable and easy to wash, which is a big plus for pool days. Love the colors and prints, not too bulky. That said, getting them on a squirmy baby can be a little tricky since they snap closed. Still a great buy overall, just takes a little practice!

Great value! They are comfy for my son to wear and save money (and keep diapers out of landfills) in the long run.
These are great for my 2 1/2 year old. I was actually on Amazon to buy the iPlay brand swim diapers, but after reading reviews I felt uncertain about what size to order because there were so many complaints about them being too small. I searched for other brands and settled on this for the versatility it offers and the price.-Fit: My son is 32 pounds and this fits him on the last snap. I do question if it would fit a 40 lb child because it’s snug on him, but I also know they lean out a little as they grow, so it’s entire possible they would go up that high.-Effectiveness: I haven’t had a poop incident in these yet, but given how they fit I feel confident it would be contained well. The elastic is snug around his thighs and waist.-Value: Two of these are a similar prices as one of the other. I’m so glad I got the 2 pack because we’ve had a few days where there’s swim lesson in the morning and then we go to the pool in the evening. This gives plenty of drying time.-Versatility: I love that I can use these for my 1 year old nephew when he comes over or any other age of kid below 40 lbs. We have a pool within a block of us and we spend a ton of time there. Last summer I used disposable swim diapers and that got expensive. I wish I would’ve bought these sooner!Overall, no complaints! Definitely a good value and you have peace of mind knowing they will fit and your child can use them for a few summers.Update Aug 4th, 2016: We had a poop incident. Actually we had come home from boating. My son had been jumping off the swim step and playing in the water. We came home before changing him out of the diaper. When I took off his swim trunks I could smell the poo. I don’t know at what point he went, whether it was in the water or the one block golf cart ride home. But it was contained well in the diaper. We hosed it off and threw it in the washing machine and it came out looking new. Phew! Glad we have these reusable diapers. Since we use them daily I know they’ve paid themselves off by not having to buy throw away ones.

Great Value, Great Product
If you are a family that likes to be around the water this is a must! They are adjustable and can be around for quite some time. The adjustable buttons on it allow these to be with the kiddo throughout multiple summers. The color and design are good. The material is nice and sturdy. I have no doubt it will last multiple washes. The only down side to this is not so much the product more of the child. My son won’t sit still when putting on clothes ao the multiple buttons make it challenging with a squirmer, overall, I’ll be buying more.

Swim diapers run small, returned item
I really like the pattern on these swim diapers and it seems like they are made out of good quality material, but they were too small. I ordered the size as directed on the sizing chart (small) but when I put it on my LO to make sure they fit, they were snug around the waist, even at the largest waist size. My LO is 22lbs and the sizing chart stated the small fit up to 40lb. There’s no way my guy could put on more weight and still fit comfortably.I ended up returning and going with a different brand.

Love these!!!
I bought these for my 7 1/2 month old and they work perfectly! They are stretchy and have multiple sizes with the buttons. My son did both number 1 and 2 in these and they were very easy to clean and they dry very quickly.
