Made from sustainable recycled polyester— Uses less energy and less water than traditional polyester during production. Recycled polyester also reduces carbon dioxide emissions. Secure, 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 baby swim diaper is cute enough to wear alone, but slim enough to wear under a standard baby swimsuit. Patented design is breathable, absorbent, and waterproof—As the original swim diaper manufacturer, our patented triple-layer design offers superior function and comfort. A wicking liner to prevent diaper rash, an absorbent inner layer that doesn’t puff up or weigh swimmers down, and a waterproof outer layer to prevent leaks.
