Campers up to 5 feet 11 inches sleep comfortably under the stars in the Autumn Glen™ 50°F Sleeping Bag, even when the temperature drops as low as 50°F. ThermoTech® insulation and a Thermolock™ draft tube along the zipper prevent body heat from escaping. Packing up is made easy with roll-control fasteners that hold the bag straight as you roll and no-tie cords to keep things cinched tight for compact storage.
