Experience the wonder of Pure Wool. Wool has unique properties for maintaining body temperature, the pile traps air, provides a constant ambient temperature and has the ability to absorb moisture. Encased in 100% cotton percale with one side plain white and the other side with a white self-stripe. The wool duvet is not puffy like our down duvets, but lies flat on the bed. It is the perfect alternative to those that are sensitive to down.
