The Happy Nappy Duo is the most advanced reusable swim diaper in the world.

It’s the only diaper system you will ever need for your baby’s swim class. The classically form fitting outer layer is still the Happy Nappy you know and love, effectively preventing fecal leaks into the pool, but inside is a highly technical active silver inner layer, which is scientifically proven to kill pathogens that cause stomach bugs like Cryptosporidium, E.coli and COVID 19. Killing these bugs inside the diaper, before they can enter the water, makes the pool safer for your baby and for other swimmers too.

Working with one of the world’s leading virologists and 4 years in development, the Silver Lining inner layer is extremely gentle on babies' skin, but highly effective in destroying pathogens that can be found in fecal matter.

But, that’s not all! Because the Happy Nappy Duo swim diaper has been approved by swim schools as a double diaper system, it means you no longer need to buy disposable swim diapers to wear under the Happy Nappy. Not only will this save you money , it also helps the planet by not contributing to the millions of tons of disposable diaper waste per year, which can take up to 500 years to break down in landfill.

Long lasting, reliable and with a naturally antibacterial layer to help stop the spread infections, the Happy Nappy Duo really is the only swim diaper you will ever need.
