This flannel duvet cover set is warm winter bedding made for cold sleepers, crafted from heavyweight 100% cotton flannel that is brushed for a soft, cozy feel and holds in body heat on cold nights far better than lightweight percale or sateen. Each 3-piece set includes a duvet cover and two matching pillow shams in Full/Queen or King/California King, with a button closure and interior corner ties that keep a down or down-alternative comforter insert from bunching or shifting. This breathable all-cotton flannel bedding suits primary bedrooms, guest rooms and cabins, and layers easily with flannel sheets and throw blankets for a warm, hotel-style winter bed.
