Organic cotton, percale cotton duvet cover set. The set includes one duvet cover and one pillowcase. This wonderfully fresh, tightly woven material feels particularly pleasant and cool against the skin. Cotton percale is a fabric woven from fine threads that is particularly dense and smooth. Cotton is an easy-care natural fiber that is excellent for bedding due to its breathability. The hand openings at the top edge of the duvet cover make it easier to put the duvet cover over the comforter. Organic material, certified IDFL-025510.
