These reusable washable diapers are waterproof and breathable. Pul-inner-suede cloth wicks moisture away from your baby’s bottom, which is an excellent choice to have next to your baby’s skin. The pocket style cloth diapers allow liquid to pass right through the suede cloth into the inner absorbent layers of the insert. Unlike fleece, there is no piling of inserts. The 3-layer, ultra-absorbent microfiber insert is super absorbent. The bottom three rows of snaps (the rise) are for adjusting the size to fit a small (8-15 Ib), medium (12-25 Ib), or large (20-35 Ib), child. Simply adjust the size as your baby grows to make this diaper a one size style diaper from birth to potty training. These clothes diapers are BPA, Phthalate, Latex, and Lead-free.
