OsoCozy Unbleached Prefolds - 100% Indian cotton prefold diapers. OsoCozy unbleached prefolds are twill weave diapers that are incredibly soft and absorbent and become softer with washing.  They must be prewashed 2-3 times in hot water to reach full absorbency!  Because they are unbleached they have a nice natural cotton color to them. As with all cloth prefolds these will shrink 5-10%.   OsoCozy prefolds are the highest quality and best selling prefolds sold on the internet.
