Because silk is a very poor conductor of heat, when used with the bag closed our silk liner will help contain additional body warmth within your sleeping bag. A silk liner is also a must when traveling in hotter climates. When used with the bag open, its natural heat managing characteristics help keep the heat out, but let the breeze come through. This liner helps keep you comfortable in both extremes of hot and cold. Ounce for ounce our most versatile and efficient liner.
