Ultralight hammock underquilt; 20° F

　　The Western Mountaineering SlingLite is a luxurious and ultralight hammock underquilt. The SlingLite fits most brands of gathered-end hammocks and weighs only 13 ounces. A down underquilt is simply the best way to ensure that body heat is retained throughout the night. The SlingLite is rated to about 20° F when coupled with comparable topside insulation such as a sleeping bag or quilt.

　　Like all of Western Mountaineering's bags, the SlingLite is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.
