√ 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!
√ 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.
√ MULTI AWARD WINNING Best reusable swim nappy – Goes to The Happy Nappy Mother & Baby best reusable swim nappy 3 years in a row MadeForMums Loved By Parents & Loved By Children Junior Design Awards Baby London Right Start awards BizzieBaby awards
√ REUSABLE – The best value for money The Happy Nappy is fantastic value for money because it is reusable and developed to be chlorine resistant, meaning it works harder for longer without losing its shape or protective elasticity, as so many other nappies do. Simply rinse, roll up and reuse, time and time again.
√ OUR PLANET – it’s up to all of us to change our habits. At Splash About we are determined to save the planet one bottom at a time. The Happy Nappy is designed to be used with or without a disposable nappy and made from recycled plastic waste materials. Ensuring we don’t add to environmental damage, but actively work to stop it.
