When weights not an issue, and wet, freezing weather is, The North Face Dark Star -40 Degree Sleeping Bag keeps you warm and dry. Overlapping shingle construction prevents cold spots from developing, even after years of bagging high-mountain peaks. A draft collar and full-length draft tube seal precious warmth in, while color-coded pull cords make for easy hood and chest adjustments. Store your altimeter watch in the large chest-level pocket for easy time-checks. The North Face included a mesh storage bag and stuffsack, so youre ready to pack and go.
