Use the Slumberjack Boundary Men's 40 Degree Polyester Taffeta Mummy Sleeping Bag to stay warm and cozy in the outdoors. This sleeping bag has a polyester taffeta lining and a polyester shell, which is light and comfortable. Featuring a mummy shape, it is made for optimal warmth-to-weight ratio, since it is cut closely so there isn't extra fabric, cutting down on the weight and making it easier to carry. This sleeping bag has Slumberloft™ synthetic insulation, which will keep you warm with the use of polyester fibers. It has a stuff sack, which will give you the perfect space to pack away your sleeping bag and any other small items. It features a 40°F temperature rating, which is ideal for warm weather nights.
