Brand new set of three wool diaper covers. The pure wool pull-on diaper cover (soaker) is made in a stretchy, double-layered knit designed for extra absorbency and protection. Untreated wool actually absorbs more than one third of its weight in moisture before it begins to feel wet. What's more, wool, being completely breathable, maintains normal body temperature - not too hot, not too cold - thereby greatly reducing the risk of diaper rash associated with heat and bacterial growth.
