Disposable swim diapers have to be one of the most expensive things on the planet, so both the environment and your pocket book will thank you for buying reusable swim diapers. We love Swimmi by Bummis. The interior polyester mesh makes cleanups easy, while the coated nylon layer traps even the biggest mess inside and away from the pool. Fabric is soft on baby’s skin and is made with UPF 50 protection. Plus the designs, like Bubbles seen here, are ultra cute.
