FuzziBunz diapers are so soft, comfortable and easy to use! They are made from a waterproof exterior and a soft micro-fleece interior. The soft outer material acts as a moisture barrier keeping all wetness and messes where they belong, preventing leaks. Buttery soft micro-fleece is the material next to the baby's skin wicking moisture away from the baby to help keep your baby dry. The moisture is drawn into the insert or prefold in the pocket of the diaper.The new and improved FuzziBunz diapers have stretchier elastic around the legs to better hug baby's curves, noticeably larger tabs for a better grip and to better prevent sagging, and updated top stitching for added reinforcement of seams. All you need to do is stick the included insert into the diaper's "pocket", snap it up, and go!!
