Trim, lightweight, and comfortable swim diaper encourages swimming—Baby will move freely during swim lessons without feeling weighed down. No bulky fabric and extra snaps. Our 2-in-1 baby boy swimsuit and reusable swim diaper is all you need for playtime at the pool or beach. Patented design is breathable, absorbent, and waterproof—As the original swim diaper manufacturer, our patented triple-layer design offers superior function and comfort. The wicking liner is breathable against baby's skin and helps prevent diaper rash. The inner absorbent layer helps protect against messes outside the pool without puffing up, while the waterproof outer layer works with the snug-fitting waist and legs to offer secure protection from accidents. No other diaper necessary! Economical and creates less waste. UPF 50+ sun protection.
