The Gingerlily winter weight 9-11 tog 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 fibre, 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.
