√ QUALITY WITHOUT COMPROMISE ON COMFORT Made from super soft neoprene and the highest-grade Lycra, the Happy Nappy is designed to be gentle on baby’s skin. With no tight elastic and no skin chafing it has been developed to move as your baby moves, so it won’t leave red marks. Regularly voted the most comfortable swim nappy available, and because there are no poppers or Velcro, the Happy Nappy is the most secure, leak proof swim nappy available.

√ ORIGINAL LEAK PROOF – The best choice you can make. The Happy Nappy is famous for its poo protection. Ensuring poo stays in the nappy and doesn’t leak into the pool. Which is why parents and swimming teachers in over 60 countries recommend babies and toddlers don’t swim without one. 99% of all swim schools insist that the Happy Nappy is part of the double nappy system needed in swim class. Our commitment to a leak free swim, means that there hasn’t been a reported poo leak anywhere in the world from a Happy Nappy in over 6 years. Now that’s impressive!
