MADE FROM SUSTAINABLE RECYCLED POLYESTER- Uses less energy and less water than traditional polyester during production. Recycled polyester also reduces carbon dioxide emissions. 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. SECURE, LIGHTWEIGHT, AND COMFORTABLE SWIM DIAPER ENCOURAGES SWIMMING-Baby will move freely during swim lessons without feeling weighed down. No bulky fabric, our baby swim diaper is cute enough to wear alone, but slim enough to wear under a standard baby swimsuit. NO OTHER DIAPER NECESSARY! ECONOMICAL AND CREATES LESS WASTE-Save money and reduce waste with our machine-washable, reusable swim diaper compared to disposable swim diapers. EASY ON-AND-OFF ELASTIC WAIST-Convenient for diaper changes while on-the-go.
