Maybe this is a good product? I guess I will find out in 6 months or so? I was suspicious when I ordered this when the size chart was for generic Amazon "baby" sizes, but took a chance anyway. That was a mistake. Now I have a swim diaper that won't fit till my girl gains a good 6 pounds. WTG Amazon.

Here is the size chart from the actual product tag:

Small: 10-18 pounds; 6-months
Medium: 18-22 pounds; 12 months
Large: 22-25 pounds; 18 months
X-Lrge: 25-30 pounds; 24 months

I used these diapers with my son for 5 months last year, in both swimming pools and a fresh water lake. He weighed around 25-28lbs and wore 18mo sized pants for most of that time, so the Large fit perfectly - you Have to have a snug fit in the legs. They are a bit sheer when wet, but the padding in the crotch area make it still ok to use w/o swim trunks over them if you forget them.

Most important - THEY DO HOLD IN POO! Between my husband and I, we had at least 3 big poos over the summer - and the diapers NEVER LEAKED POO. That being said, because you have to peel the diaper down off the kid, it is almost impossible to get the poopy diapers off w/o a bit of a mess. But at least you don't have to worry about causing a health crisis/shutting down the local pool b/c of a poo leak.

They wash easily, and even survive a few accidental runs through the dryer. We took swim lessons 2-3 times a week, and only needed 3 diapers to get us through the summer.

One last note - don't change into the swim diaper until you are ready to get in the pool. Like all swim diapers, they are designed to hold in the poo, not urine. So if he wets himself on the way to the pool wearing the swim diaper, everything is going to get soaked.

We bought this swim diaper along with the Bummis and Flap Happy brands for my 12 month old. This swim diaper definitely is the best in terms of padding/absorbancy, sizing, and leak-proofing.
The other two brands, in comparison, just have mesh linings whereas the iPlay has something similar to a cloth diaper lining inside in addition to the mesh, plus elastic around the top & legs. I thought the outside of this diaper was going to just be regular cloth like the Flap Happy brand, but it's actually more like a water resistant shell. I really trust this diaper on its own in the pool versus the other two.
There is also a really cute little blue accent tag at the top.
I do like the styles/patterns of the other two swim diapers (black sharks on the Flap Happy and blue clown fish on the Bummis) but this diaper seems to be the best quality and leakproof, which is what really matters.

Wonderful product. When our neighborhood pool started requiring a swim diaper and rubber pants for any child under 4, I was a little anxious as our 2-yr old was already potty trained and was worried about all the layers and her being confused about wearing pants now. I love how this product is all-in-one so she just can wear these under her suit. Not terribly bulky, washes well and you save money buy not having to buy the disposable swim diapers. Bought another pair for my 6-mo old as well.

a must for the summer! get at least 2 for a vacation, maybe 3. They take a while to air dry.

This swim diaper is great to use since disposable swim diapers are so expensive. It is easy to get on and off with the side snaps as well. And realize that those people that complain that it doesn't work don't understand the purpose of a swim diaper. It will not keep the urine from leaking - it is purely to keep the solids from going into the pool. That is pretty much how all swim diapers work, or else you would have a 50 pound baby coming out of a pool! So just put the diaper on right before going into the water and switch it out for a regular diaper when you're done. The sizing off the product's label (don't follow amazon's sizing) is as follows: small is 10-18 pounds, medium is 18-22 pounds, large is 22-25 pounds.

I bought size 18 months for my 22 lb, 9 month old boy. The diaper fits well and is thin enough to fit under any swim trunks. We tested it out on vacation and it worked fairly well - it caught the poop (although would probably not hold up too well with loose/runny poop), but didn't hold up well as far as absorbing pee. If you plan on spending a day at the beach or pool, you should plan on getting several of these to change every couple of hours or so.

We normally use cloth diapers for our little one and have been using the pocket diapers without the insert as swim diapers. Those work awesome, absorb well, and don't weigh the baby down when they're soaking wet as much as the iPlay diaper does (surprisingly). If you are already a cloth diaper user, I would recommend this alternative as opposed to spending the money on this diaper. If you are new to cloth diapering, the iPlay Swim Diaper is a great way to experience how easy it is to use reusable diapers, save money and save the environment while you're at it.
