The Nageuret Reusable Swim Diaper by B B Littles is adjustable for infants and toddlers. The cloth diaper comes with three preset sizes that allow the diaper to grow with your child. Made from PUL fabric out that keeps solids in, soft elastic around the waist and legs for a tight fit and ultra soft polyester inner that keeps rashes away from skin. Take this all in one diaper to the pool, beach, or other body of water for memories with your little boy or girl. As a reminder swim diapers are only designed to contain solids, so we recommend changing just before going swimming. If you need breaks between swimming adventures, the swimsuit diaper will dry quickly and be ready to use when you're ready for the next adventure.
