Head to pool or beach with a smile! Swim nappies are desired by most swim schools and pools. Happy Nappy diapers fit sweet and snug thanks to nylon lycra ribs at the waist and thigh. Have confidence in effective protection against those unwanted nasties - all the you-know-what is kept out of the pool and away from fellow bathers. Easy to clean, rinse, roll and reuse. Wear alone or over your favorite swim diaper for extra protection!
