The Sierra Designs Nitro 15 Degree Sleeping Bag. Ultralight 15° F / -9° C You won't believe how much warmth and comfort you get from such a small package - the Nitro packs into a tiny sack (included), but stays toasty to 15 degrees. We build in Flex between the shoulders and knees, so you get the comfort and thermal benefits, while saving precious ounces. Continuous baffling and a draft tube contain 800-fill goose down, the warmest, lightest insulation available.
