    • Absolutely does the job!!
Color: Red,yellow Size: 3-4 Year
I was unsure about buying this but we just recently moved to a house with a pool and constantly buying swim diapers seemed wasteful. This does the job, has been tested thoroughly by my baby. Takes a couple times to figure out how to get it on easily. Super easy to clean. I'll be buying another soon!! If your one the fence, just buy it. ... show more

This swim diaper is so well constructed. I love the duo better than the regular ones and will always buy them from now on. They do a great job of holding accidents in.

    • It works!
Color: Noah's Ark Size: 12-24 Month
We bought these for our grandson for a Christmas vacation. We knew we would be in the pool everyday and needed something to prevent accidents. These worked! We used a disposable swim diaper and put the Happy Nappy over top. No number 1 or number 2 leakage. I don't know if the Happy Nappy would be sufficient on their own as we did not try but they worked great with the disposable swim diaper underneath. These are easy to get on and fairly easy to get off. I expected them to be a little harder to get off once wet but they were not as bed as I thought. I would do the measurements for sizing as the seller suggests. The first order I went by age and it was too large. I quickly reordered the size down and it fit like a glove. I kept the larger pair because the grand baby will grow into the larger pair by the summer. I highly recommend these swim diapers. ... show more

    • Great reusable swim diaper
Color: Blue Cobalt Size: 2-3 Year
Love these for my 2 year old boy. They are required to wear these for swimming lessons and they fit and keep everything secure. They dry fast and are easy to take on and off. He has not had an accident in them yet, so I can’t speak to how they hold everything in if that was to occur.

So far they work great, but my son hasn’t pooped in them yet, that’s when the real test will be

    • Very functional.
Color: Vintage Moby Size: 2-3 Year
They are a wetsuit material and snug which really helps to seal in everything. Only bought these because the swimming class required them. They keep everything in the one time it happened to another kid in class. They fit well but would say standard sizing is a tiny bit on the slender sizing. Just measure to double check. They get pretty tight if closer to the higher size. Much better than the water absorbing swim diapers. ... show more

    • No leaks
Color: Flower Meadow Size: 12-24 Month
Best swim diapers for babies that aren’t potty trained. Fit to not leak!

    • best swimming diaper
Color: Vintage Moby Size: 2-3 Year
got this for the swim school but turns out it is the best swim diaper that I have owned for my kid. There is a tight fabric on the belly and legs to keep solids in if there is an accident. But it is not too tight where the kid is uncomfortable.
