Baby can move freely when learning to swim. Reusable Absorbent Swim Diaper made with cute designes to choose from. Stretchy and lightweight material, and comfort seams. Along with comfort, Swim Diapers have many functions, so baby does not need to wear any other diaper in the water. The wicking liner helps prevent diaper rash, the inner absorbent layer helps protect against messes outside the pool, and the waterproof outer layer works with the snug-fitting waist and legs to provide secure protection from unsanitary and embarrassing accidents in the pool.
