The OsoCozy Unbleached Prefold is a prefold diaper insert. For this review, we tested only the OsoCozy prefold, not their cover. This prefold can be used with just about any cover. To estimate lifetime cost for this particular prefold, we factored in the lifetime cost of the Thirsties Duo Wrap along with it. The OsoCozy Prefold is made up of several layers of rectangular fabric sewn together along the edges. The prefold needs to be folded in a particular way depending on the size of your baby and where he/she needs the most absorbency and is then placed into the cover. Figuring out the correct folding technique can be difficult if you are new to cloth diapering and is an additional step in the preparation of the diaper. Like other prefolds, leaking is rare, but they don't always effectively pull moisture away from the surface to keep baby feeling dry. They have the ability to absorb a lot but they are quite thick and bulky.
There is no denying that these diapers work and will do the job, making them a practical and cost-effective choice. While prefolds are a tried and true form of cloth diapering, the technology has come a long way and there are other types of inserts that we prefered after completing our testing.
