Lauren: a few months ago

Super cute, quality design and material but I already have it on the biggest size on my little guy who is only 23 lbs. He also pooped in it first thing before we even got to the pool, so I can attest it holds up well with poop. Bonus: it's easy to clean!

Amanda: a few months ago

This is my second swim diaper that I have bought from, same company because I loved the first so much with my first son, bought this one for my new lasts for so long b/c of the adjustable snaps!

Kristina: about a year ago

A great swim diaper. My son is 26lbs and is on the largest size but this fits him just right. Love the material and quality!

Angie: about a year ago

Love the material, one size and print although it seems a little tight on my little guy who is only 29lbs.

Zoey: about a year ago

GUOYAN: more than a year ago

Prepare for his first swimming class,yeah...

Robi: more than a year ago

Works great, even for "solid waste", not sure it will fit our little chunked all the way to 40lbs but so far so good.

Kika: more than a year ago

Colorful! I love that it's a one size fits all since we have two boys under two.
