So light and so comfortable....it's like sleeping on a cloud. Hailed by Outside Magazine as one of the "best sleeping bags for backpacking," the Women's Cloud 20 is the envy of all mummy bags - an oversized, zipperless sleeping bag that provides unrestricted freedom for any sleeping position. A natural choice for 3-season adventures in the backcountry, it's stuffed with ultra-compact, responsibly sourced 800-fill DriDown(TM) and coated with PFC-free water repellent. And with our adjustable self-sealing foot vent, insulated shoulder pockets and a sleeping pad sleeve, hot sleepers and side sleepers alike can snooze comfortably in cloud-like comfort when roughing it down on earth.
