The Autumn Trails big and tall extreme weather sleeping bag is built for temperatures down to 20 Degrees Farenheit. The Autumn Trails bag fits most people up to six-foot, four inches tall, with overall dimensions of 39 inches by 81 inches and box corners at the bottom that give your feet plenty of wiggle room. Campers will also love the rolled-top hem and FiberLock stitching, which combine to cleverly anchor the Hollofil 808 insulation ï¾ comfortable down to 20 degrees F ï¾ so it won’t shift, bunch up and get lumpy during the night. As a result, sleepers can avoid cold spots and enjoy a far more durable performance over time. For even more warmth, the bag offers Coleman’s Comfort Cuff system, which surrounds your face with softness. Finally, the bag is fully machine washable, with a cotton cover and cotton flannel lining that stand up to tough conditions.
