Swim Diaper by Thirsties

Is that a Duo Wrap? Close, but no! Thirsties new swim diaper is modeled after their Duo Wrap diaper cover system, but trimmer and lined with mesh. It also has hip snaps to ensure a snug fit that does the job of keeping solids in! Bonus - cute new beach bum Thirsties summer prints!

Duo style means only two sizes, each with built in adjustability. That means you buy less sizes over time, saving even more money! With most brands, you have to buy a new size of swim diaper each season - not so with Thirsties! Two sizes will take you through the diapering years!


Swim instructors and life guards love reusable swim diapers; they simply are more effective at keeping solids in! Snug fit and double gusseted legs really do make a big difference. If poop does not happen while in use, simply rinse and hang dry. If solids happen, unsnap and remove the diaper, rinse soiled matter, wash, and reuse!

Pair with a Wet Bag in a matching print and you are all set for swimming!
