4x8x4 ply thick layers of soft cotton for your baby's bum. Pure 100% cotton unbleached twill weave prefold diapers. These diapers are incredibly soft and absorbent and become softer with every wash. Don’t be surprised at how stiff they appear at first. Wash these diapers a few times in hot water and they will fluff up beautifully! Because they are unbleached they have a natural ivory cotton color to them. They will shrink 5-10%. Diapers measure 15 1/2" x 12".
