Best swim diaper

Love this swim diaper, it’s not bulky and doesn’t hold water like the other ones we’ve used.

Not bulky, colorful

I have never used a swim diaper before so I’m not sure what they are like but my 14 month old 25lb baby got the 12-18 month size and it fits perfect right now but probably won’t fit for the entire summer. After the first use it has sand stuck inside the fibers.. that might be normal for any swim diaper since he was sitting in sand. I got this on sale so it’s worth it to me. Also it’s hard to find swim diapers that are not blue so I appreciate the brighter colors. I read the other reviews and thought the next size up might have been too big but I’m thinking I probably should have gotten 18-24. My baby is more thick built.

Quality product

Fits my baby really well for the pool, snug but not tight. Definitely secure over a swim diaper.

Perfect swim diaper

This is the only reusable swim diaper I've found that fits my kid well! It's big enough to fit him comfortably, fitted enough to avoid leaks, and the elastic is soft and flexible (other reusable diapers we've tried have firmer, tighter elastic that pinches him and leaves marks). It was an absolute bargain at the end of season sale so I bought the next size too!

Not a swim diaper, more like a diaper cover

Not a swim diaper. More of a swim bottom and diaper cover. Baby leaked right out of the sides

Best swim diaper

These swim diapers are great. They're very stretchy and will last for a long time. Stay on securely but comfortably. We love to mix and match with primary swim tops
