With the invention of the Nitrous Jacket, Mountain Hardwear created a lightweight and non-bulky down jacket that is still incredibly warm. This jacket has hand pockets and elastic cuffs for extra warmth. The Nitrous Jacket also has a zippered chest pocket for extra storage and a hem drawcord for a perfect fit. Mountain Hardwear has a reputation for attention to detail, and this jacket is no exception. With a soft Micro-Chamois™-lined collar to prevent zipper chafe the makers of the Nitrous Jacket thought of just about everything. Climbers, mountaineers, hikers and backcountry explorers will especially like this jacket. Its recycled polyester blend fabric is good for the environment that fans of the brand love to explore so much.
