If your budget says you don't need the best than check out this bag. The Sojourn might not pack as small as the others in this list yet it is still a roomy yet lightweight, compact, warm and water resistant mummy bag? Designed to protect and comfort you from the elements, these bags feature dual zips, "arms-out" and their DriDown technology. DriDown uses a proprietary treatment to create a hydrophobic finish on each down plume, allowing the insulation to stay dry longer, loft better & dry faster than untreated down. Slumberjack's unique "arms-out" feature allows you to keep insulation on your chest and head while freeing up both arms to manage tasks without leaving your bag.
