Introducing the OsoCozy® All-In-One Cloth Diaper The first and only all-in-one cloth diaper made of the same wonderfully soft 100% cotton gauze that prefolds have been made of for the past 50 years. The OsoCozy All-In-One features a contoured form fitting shape with a soft PUL (Poly Urathane Laminate) waterproof liner and durable Aplix brand hook and loop closures. The interior gauze layering is a little thicker than in typical prefolds to provide extra absorbency. Manufactured in the USA by stay at home moms and grand moms! A wonderfully simple and basic all-in-one cloth diaper at a great low price.
