A North Face favorite, the Superlight Sleeping Bag is a zero degree technical down bag for mountaineering and cold weather camping trips. The Superlight features an ergonomic face and neck gaskets that keeps heat inside, a vaulted footbox, and a full side zipper. The 650+ down fill is both efficient and effective. North Face also added a lot of details to the Superlight sleeping bag including buttery soft fabric, a compression stuff sack, glow in the dark zipper pulls, and a small pocket at the top of the zipper.
