A true winter sleeping bag, the Therma a Rest Women's Adara HD Sleeping Bag will keep you warm when the temperatures plummet with a comfort rating of 22 degrees Fahrenheit. Great for winter camping, this lightweight pack weighs just about 2. 5lb, so it won't weigh you down when you're moving quickly through the backcountry. The exclusive ThermaCapture reflective lining captures your body's radiant heat to add warmth without adding weight or bulk. And for cozy toes, Therm a Rest's patent pending Toeasis pocket gives your feet their own little chamber to make it easier to stay warm. Hydrophobic down will remain warm if it happens to get wet, and the zoned insulation places 85% of the fill at the top of the bag, leaving the Synergylink mattress connectors allow your mattress to do most of the insulating between you and the ground. The full length zipper is backed by an insulated draft tube, and the bag's cinchable hood with draft collar let you hunker down for warm night's sleep in the depths of winter.
