Better Fit also called Trifold prefolds tuck into a diaper cover without folding like an insert and make cloth diapering so easy. No extra twists. No pins or fasteners needed. Just tuck, wrap, and done. See folding instructions in the images. Add diaper covers for the waterproofing component of your complete cloth diapering system. Made with soft, durable unbleached cotton gauze. These prefolds "quilt" or "fluff up" nicely but require 3 pre-washes for absorbency. These cloth diapers are thick, very absorbent, and lint free.
