Sleeping bag ideal for campers up to 5 feet 11 inches to sleep comfortably under the stars, even when the temperature drops as low as 50 degrees Fahrenheit. 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.
