The Slumberjack Ultimate Regular Mummy Sleeping Bag is packed with value, but not weight! It weighs a mere 3lbs 2oz yet its rated to 20 Degrees.

The Double offset, differential cut construction eliminates cold spots. The flip Over Hood allows users to flip the hood inside out giving the option of a flat hood or a fully contoured hood. This bag includes Easy Access Drawcords with Barrel Lock Closures permit closure of drawcords on hood and storm collar. The cords are either flat or round, allowing users to easily adjust storm collars and hoods in low light situations. Hook and Loop Closures provide firm closure of the bag and prevent zippers from separating or opening. Anti-Snag Zipper Protection is sewn along the draft tube and zipper to ensure reliable zipper operation. Internal Collars are baffles sewn to the liner, used to prevent heat loss from the neck and shoulders. Draft Tubes are baffles sewn adjacent to the zipper to keep cold air out and prevent heat loss through the zipper coils. Weather Wedge is a small piece of triangular fabric that is sewn at the base of the zipper to prevent heat loss at the zipper's bottom. This also reduces stress at the point where the zipper is sewn for greater durability. Vented Foot Box (patent pending) zips open to provide added room and thermo regulation for maximum comfort in a wide-range of temperatures and environments. Trapezoid Foot Box provides space in which the feet remain in a natural position for better comfort.
