Happy Nappy™ Swim Diaper
First swim coming up? The Happy Nappy™ Swim Diaper is the one parents and swim schools have trusted since 2005. Soft 1mm neoprene seals snugly at the waist and thighs to keep solids in, with no disposable underneath.
Fit Your Reusable Swim Diaper
You should be able to slide a finger under the seals with no red marks left behind. Measure first, as we can only take back unworn items within 30 days.
Does Your Swim Class Need a Double Diaper System?
Some swim schools ask for one, so check with your instructor. Our Silver Lining Diaper Wrap goes underneath your Happy Nappy™, and the Happy Nappy Duo™ adds an inner layer that helps protect against germs.
Does the Happy Nappy™ Hold In Urine?
No, and it isn't meant to. Water flows in and out so it never gets heavy, which means urine passes through too, just as with disposable swim diapers, so change your baby into a regular diaper afterwards.
Why Parents Choose Splash About
It's award-winning and recommended by many swim schools across the US and Canada. Not sure which size suits? Email us at info@splashabout.com and we'll help.
Frequently Asked Questions
Not a disposable one. The Happy Nappy™ is designed to be worn on its own for general swimming, inflatable pools or the ocean, and its seals keep solids in without anything underneath.
Only if your swim class asks for a double diaper system, so it's a good question to put to your instructor. If they do, the Silver Lining Diaper Wrap goes on first, with the Happy Nappy™ over the top.
Right here, in every print and size we make. Browse the collection below, and if it's your first one, measure your baby before you pick a size.
For most babies, we'd say a reusable neoprene swim diaper that seals snugly at the waist and thighs, because that seal is what keeps solids out of the pool. It's why the Happy Nappy™ tops our list of the best swim diapers, though we'll admit we're a little biased.
Go by measurements rather than age, since babies the same age can be very different sizes. Lay your baby flat, ideally not straight after a feed. Measure around the tummy across the belly button and around the fullest part of the thigh, then check both against our Happy Nappy™ swim diaper size chart.
