The Sierra Designs Nitro 30 Degree Sleeping Bag. Ultralight 30° F / -1° C Going Ultralight doesn't have to mean suffering. We'd rather find a way to shave the weight and innovate on performance, like using Flex technology for our Nitro 30. We build in Flex between the shoulders and knees, so you get the comfort and thermal benefits, while saving precious ounces. Foot Box Venting lets you customize the climate in the lower half of your Nitro, without adding the weight of a full-length zipper. Ultralight speed with full-featured comfort.
