Question: do reusable swim diapers work?
Answer: A reusable swim diaper makes a lot more sense. Neither one will keep pee out of the water; they're not designed to. Their job is to keep poop from leaking out into the pool, and both do an okay job of it. Reusable swim diapers are made of a mostly-waterproof fabric, and they velcro on like a regular diaper.
