Nappy service quality meaning these are the same kind of thick and absorbent cloth nappies typically used by nappy services. OsoCozy prefolds are a step up in quality and value from many store brands. 12 by 16 inches before washing they will shrink approximately 10% like most cotton products. This size fits babies from 3 to 7 kg and is generally used with a nappy cover or plastic pant. These three paneled rectangular nappies are 4 layers on the sides and 8 layers thick in the middle. OsoCozy prefolds are the highest quality and best selling cloth nappies sold on the Internet. Note that our unbleached nappies must be washed and dried 2-3 times prior to use. This initial washing is required for the unbleached fabric to achieve maximum absorbency by removing natural cotton oils from the fabric.
