The Cloudveil Women's Koven Jacket utilizes Cloudburst Stretch EV3™ fabric, a storm-sealing hood and an advanced DWR finish to provide the function, style, and protection of a true alpinist shell. The waterproof/breathable fabric with built in mechanical flex, stretches during ski tours, ice climbs or summit bids, without compromising the integrity of the fabric. Internal bio mapping places fleece against the back for warmth. Although built to be as lightweight as possible, the 50 denier fabric of this jacket will endure countless hours of heavy use. Pit zips cool you down when going hard. Climber, hikers, alpinists, and skiiers will all love this jacket equally. A true hard shell for the serious mountain adventurer.
