New for 2013. 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 Antares sleeping bag offers ultra light performance without sacrificing the warmth and comfort you need. The result is a restful night of sleep and another great day on the trail.
