The Therm A Rest Women's Adara Sleeping Bag is the warmest women's bag in the line. A true winter bag, the Adara will keep you warm into the single digits for cold weather camping, but it still weighs just 2. 5 pounds, so it won't weigh you down when you're moving quickly through the backcountry. Therm A Rest also added extra down in the bottom and a draft collar to really lock in the heat when overnight temperatures plunge. The exclusive ThermaCapture reflective liner captures your body's radiant heat to add warmth without adding weight or bulk. Therm A Rest's patent pending Toe Asis pocket gives your feet their own little chamber to make it easier to stay warm. The 3D baffling with a shingled top eliminates cold spots, and the Synergy link connectors keep your bag centered on your sleeping pad no matter which position you like to sleep in.
