The wool cover is two layers of super soft, undyed interlock knit wool. This is one of my favorite fabrics! It's not certified organic, but it's the next best thing; plus, it's incredibly soft with a nice stretch for a great fit.

Features:

Strong Touchtape closures

Leg gussets to contain messes

Under the belly button fit for newborns

Edges are finished with soft serging

Wool covers are great for heavy wetters and nighttime use. CYA Wool Wraps fit well over my fitteds as well as other brands and prefolds. Elastic in the leg gussets and back waistline are great at controlling leaks and provide a comfortable fit.
