The backcountry can be a demanding place whether it's summer, spring or fall, late snowstorms and early frosts often come unexpectedly. These conditions require a sleeping bag that is warm down to 20F (-7C) and light enough to go the distance on the trail. The award-winning, down-filled Therm-a-Rest Antares sleeping bag offers ultralight performance without sacrificing the warmth and comfort you need. The result is a restful night of sleep, and another great day on the trail. Also features draft tubes & collar, snag free zipper, stash pocket, sculptured hood and trapezoidal footbox.
