100% cotton gauze weave cloth prefold diaper in heavy, night time weight, 4 x 8 x 4 ply. High quality cotton birdseye fabric is soft and absorbent. These are long lasting, high quality diapers. Many prefold diapers are constructed with a terry or foam filler where the diaper is doubled. This can lead to the growth of bacteria and increase the dry time. Our diapers are cotton gauze all the way through. These diapers will shrink after washing. The large size will shrink approximately 10 percent in length and less in width. They will continue to shrink for a dozen wash dry cycles. They will also fluff up and grow softer with each washing.
