Our swim shorts for Big Cubs offer all the security of a swim nappy but in a more grown up, sporty design. Potty training is an exciting time and wearing a swim nappy to swim class can feel like a backward step, but not with these swim shorts. Designed to work in the same unique way as the swim nappy, the specialist fabric at the waist covers the base of the spine, whilst medical grade silicone forms an effective seal on the thigh. This ensures that if there is an accident it stays firmly in the shorts and doesn’t leak into the pool.
