Sierra Designs Nitro 15 Sleeping Bag - Regular Left 500152

You won't believe how much warmth and comfort you get from such a small package - the Sierra Designs Nitro packs into a tiny sack (included), but stays toasty to 15 degrees. Sierra Designs builds 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.
