These patent pending Jammers provide your child with all the assurance of a Happy Nappy but in a more grown up and sporty design. We understand how exciting potty training can be and wearing a swim nappy to swim class can feel like a backward step, but not with the new Jammers. Designed to work in the same unique way as a happy 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 should a faecal accident happen it stays firmly in the jammer and doesn’t leak into the pool.
