This is the patented sleeping bag with zippered vents that let you cover only as much of your body as you wish. Four outer zippers that span across the sleeping bag near the ankles, knees, waist, and chest allow campers to selectively cover or uncover any body segment as the temperature or personal preference dictates. The rectangular bag has an outer shell of 210 thread-count rip-stop nylon, a soft cotton flannel lining, and is filled with four-layer microfiber insulation rated to 20º F. An included pillow slips into a built-in sleeve to support your head. The sleeping bag can also be worn indoors to help one keep perfectly cozy while watching television or reading. Includes nylon stuff sack. For users up to 6'1" tall. Blue. 72" L x 31" W x 3" D. (5 1/2 lbs.)
