High Quality and Cute
Super cute design, Great quality of material, and has held up well with multiple washings. The color does not fade in the chlorine. The fit is both comfortable and functional. Great swimsuit!

Loved.
Got this instead of disposable swim diaper because the minimum weight did not fit my 3 month old. These worked very well & baby did not seem uncomfortable. Slightly tricky to get on, but was as expected since they need to be tight to work. I have not washed it in a machine yet, but has held up through a sink wash so far.

Love it!
Love it use it for swim classes! Great price great quality. There is definitely a method to put this diaper on. It is designed tight around the thigh area so that the diaper contains accidents the baby has. Baby might need some getting used to but it’s awesome and we have been using them for a little over 1.5 years.

Comfortable and Functional
This swim diaper works great! The design is so cute. It’s a little bit tough to put on because it’s a tight fit, but the snug leg holes/waistband is what makes it work so well! It looks comfy for my baby girl and doesn’t leave and marks.

Nice swim diaper!
Leakage: Zero leaks of number 2! (Yes, unfortunately we had to experience this). Unfortunately not leak proof with urine. Durability: Very durable, with wet-suit material! Ease of cleaning: Easily cleaned due to material. We sprayed out with the hose and put through the washer.

Best swim diapers
Best swim diaper around. This was recommended by all of our swim teachers. These are perfect for babies and toddlers. These do not absorb pee, so put them on right before you take the little one in the pool. You will not be disappointed.

Pricey, but I like it.
My daughter is 36 inches and weighs 35lbs. The 2-3 year fits her just fine. Easy to put on. Easy to take off when wet. Haven't had a poopy accident, but the swim school recommended this brand so I believe this will hold uo just fine. No out of the package smell, but I did was it before use and there is no shrinkage.

Perfect for swim class
My toddler’s swim class required us to use these instead of disposable swim diapers. They fit as expected, are cute enough to not need to put swim bottoms on over them, and are very comfortable! My kid never pooped in them so I can’t attest to how well they keep things in, but they are very thick and durable so I would think they could handle the mess!

Too small!! My grandson is 12 months old… very average size for his age. These are tight all over but especially on his legs.

The best swim diaper! I’ve had my baby in swimming lessons since he was 5 months (he’s now almost 2) so it’s the third of these we’ve purchased as he’s gone through 3 sized. We layer this over a disposable swim diaper for double protection. The designs are always adorable, and they hold up incredibly well in the wash (they’ve been through weekly washes and are still as bright as the day we bought them). Very easy to pop on and off, even on a wet, squirmy baby. Fits well and very effective. The best reusable swim diaper on the market, hands down, even when compared to the pricier ones. Would recommend to anyone.

Great quality and will not let any accidents escape. The Happy Nappy fits nice and snug and is very comfortable. My grand babies love this swim nappy and so do I.
