Best Bottom shells are your one-size solution for easy diaper changes. Part of the Best Bottom Diapers All In Two system, the waterproof shells are wipeable and reusable. Rise snaps on the front of the diaper shell allow the size to be adjustable, fitting babies 8-35+ pounds.
Best Bottom shells are composed of one inner layer of PUL (polyurethane laminate) waterproof material that's sewn on the inside of the shell and one outer layer of polyester that's backed by an additional layer of PUL. Double gussets on the shells is another feature to love about the Best Bottom Diapers system.
