The Skinny

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.

Our Analysis and Test Results

Affordability is one of the main reasons that many parents choose to go with prefolds rather than other cloth diaper systems. They tend to be considerably less expensive than other types of inserts out there.

For a small step up in cost relative to budget-minded prefold options like the Gerber Prefold, the OsoCozy Unbleached Prefold delivers a meaningful increase in comfort and quality. They scored slightly higher overall than the Bummis Organic Cotton Prefolds and also cost less, but they are not made from organic cotton. If this is important to you, OsoCozy does offer a prefold option in organic cotton (as well as another in bleached cotton).

The OsoCozy Unbleached Prefolds are available in two sizes: Size 1 (7-15 lbs) and Size 2 (15-30 lbs). The unbleached cotton fabric stays soft after washing and had minimal pilling over time. The edges are sewn precisely and the corners are neatly finished. It seems that these prefolds will hold up well and stand up to a lot of use.

If you have a preemie or a late potty trainier, OsoCozy has Unbleached Indian Cotton Prefolds which are available on Amazon in four sizes: Preemie (3-7 lbs), Infant (7-15 lbs), Regular/Premium (15-30 lbs), and Toddler (30-45 lbs). Obviously, the more sizes you need to buy over your child's diapering days, your lifetime cost for the OsoCozy Prefold cloth diapering system will increase.


Prefolds in general are absorbent and seldom leak, but oftentimes, baby can feel the wetness. This diaper didn't score well in our lab testing for absorbency, a disappointing 2 of 10, and didn't seem to have any kind of effective wicking layer to draw moisture away from the skin.


Although this OsoCozy prefold scored 2 of 10 in our absorbency testing, it scored an 8 of 10 in fit-leakage because it does have the ability to hold a lot of liquid.

This prefold can be used in conjunction with any type of waterproof cover to hold it in place, like the Thirsties Duo Wrap or it can be folded to fit baby and secured with a Snappi (see below) before a cover a waterproof placed over it.


Prefolds in general are so bulky and this one is no different, which affected its score in the "comfort" category. These prefolds are thick between the legs, seem to make it more difficult for baby to move around and, in our opinion, just aren't as comfortable as some of the slimmer cloth diaper options out there. It can also be hard to fit tight clothing over them.


A prefold insert requires folding in order to fit it into the cover, which is an additional step in the preparation process and can be a nuisance.

In addition, the OsoCozy Prefold can be folded and fastened without a cover with the use of a Snappi diaper fastener (see below), which we recommend take the place of outdated, cumbersome, and risky pins.

Nonetheless, this prefold is easy to care for in the laundry. It's made of cotton and doesn't require any of the special care that synthetic fabric sometimes do, such as "stripping".


This prefold is simply 100% unbleached cotton, no synthetics, and scored an 8 of 10 in eco-health. As mentioned above, OsoCozy does offer an organic prefold option as well. The next step is figuring out which type of cover to use with this prefold. For our lifetime cost comparision, we factored in the Thirsties Duo Wrap with PUL (PolyUrethane Laminate waterproofing) to accompany this insert.


The OsoCozy Prefold Unbleached landed 10th out of our round-up of 15 cloth diapering systems. It performed best on our fit-leakage metric scoring a 9 of 10 and is a great choice for those desiring a cost-conscious way to cloth diaper their little ones with all natural fabrics. However, cloth diapering technology has come so far and, in our opinion, there are thinner and easier diaper inserts on the market that can do a better job at keeping your baby both comfortable and dry on the surface.
