About this item

Product details

The Happy Nappy Duo™ is the world’s first reusable swim diaper with a built-in silver-lined inner layer, designed to destroy germs from poop within the diaper. Approved by many US swim schools as a complete double-layer diaper system, it’s designed to be worn on its own, meaning no more disposable swim diapers — ever. Better for the planet and your wallet. Trusted by parents and swim instructors in over 60 countries, the Happy Nappy Duo™ offers unbeatable leak protection, keeping fecal accidents contained and pools clean. Made from premium neoprene, it’s soft on sensitive skin, helps soothe irritation, and is free from tight elastics, poppers or Velcro style fastenings — ensuring a snug, comfortable fit without red marks or chafing. Chlorine-resistant, long-lasting, and perfect for any swim occasion — from lessons and family swims to beach vacations — the Happy Nappy Duo™ is the only swim diaper your child will need.

Great for swim class

The swim school requires these duo suits. Ive never had my toddler go number 2 in them but they are sooo tight that i believe it would keep it inside if an accident happened. Number 1 goes right through it. Even though they are super tight my toddler has never complained and they loosen up a little once in the water.
