This swim diaper is lined with a moisture wicking fabric to help prevent rashes and keep solids contained. This diaper meets the requirements for most public pools. Swim diapers do not require any additional diaper. They are intended to retain solids, not liquids. A reusable absorbent insert may be placed inside when baby is not in the water. We do not recommend any absorbent material be used with this product in the water as it may weigh the child down. This cover may be used over a disposable swim diaper to meet the requirements of public pools. Made in the USA.

Swim diaper

Sizing runs very small

I got 3 medium sized diapers for my 25 pound 2 yo daughter. She is a 2T height, but measures under 18 months in everything else (she's a noodle) so I was confident in the sizing, but I can't put her in them anymore because, even at the loosest setting, I have to fight to get them to cover her bottom and she has thick red marks along her legs and waist after wearing them. They seem like nice diapers and they are VERY cute, but I would size up from the chart if I were you. Waste of money for me, unfortunately.


Green Mountain Diapers

Unfortunately sizing is always approximate and we ask customers to try on over protective clothing before washing - we are happy to accept returns up to 30 days after receipt of unwashed items. If purchasing much before planning on using it might be good to size up. Thank you for your feedback on the sizing!

Impulse buy that I don't regret!

The New England weather is warming up and my son is going to be spending a lot of time his first summer alone in his baby pool (thanks, COVID-19). But doggone it, he's going to look cute doing it! I didn't realize how adjustable it was until I took it out of the package, so that was a pleasant surprise. My guy's chunky but I want a snug fit to keep any solids trapped. And I just realized that the navy stripes match MY navy bathing suit!

Soft and stretchy

Ordered a size 2 for my giant chunky 4 month old. It looked so tiny that I was worried it wouldn’t fit, but it’s a soft stretchy material unlike out other swim diaper. I think it seems more comfortable. I’m super happy I tried out this brand!
