® by green sprouts® Snap Reusable Absorbent Swim Diaper. Save money and reduce waste compared to disposable diapers, which are often less secure than our triple-layer design. Our trim, lightweight baby swim diaper has a wicking liner to prevent diaper rash, absorbent inner layer that doesn’t puff up, and waterproof outer layer that works with the snug-fitting waist and legs to help prevent leaks.
