The comforter is the perfect natural choice for those colder winter months and for those individuals who prefer a fuller comforter option. As silk is a natural heat conductor and a breathable fiber, the silk floss filling adjusts to the body and to the ambient temperature of the room. By trapping air next to your skin, the comforter keeps you warm and provides a comfortable and restful night's sleep. It is filled with the finest quality pure long-strand mulberry silk. As silk is naturally hypoallergenic, it is ideal for allergy and asthma sufferers. Our winter weight comforter has buttons and small ties on its sides and corners. It can be buttoned together with a summer weight comforter or an all-season weight comforter for tailored warmth as required.
