The Happy Nappy Duo, exclusively from Splash About, is an advanced swim diaper featuring a silver-lined inner diaper designed to help neutralize germs before they reach the pool. Developed over four years with a leading virologist, the silver lining has been shown to target pathogens found in fecal matter while remaining gentle on delicate skin. This technically advanced swim diaper features a 1 mm neoprene outer and a soft silver-lined inner layer. Nylon-elastane ribs at the waist and thighs create a secure, leak-resistant seal for dependable protection, while the pull-on design avoids snaps or gaps. Recognized by swim schools as a complete double-diaper system, it can be worn on its own with no disposable diaper required. Durable and reliable, it s designed to support safe, comfortable swimming every time.
