Fast-drying protection for demanding alpine objectives

The Mountain Equipment Switch Alpine Jacket combines a 20D RS Nylon outer fabric with Octayarn Warp-knit insulation to deliver exceptional breathability, moisture management and warmth for serious mountain users. Designed for climbers, mountaineers and ski tourers tackling alpine routes, winter climbing and expeditions, it performs as either a highly breathable outer layer or a warm mid-layer beneath a shell. Double-layered Octayarn insulation in key exposure zones provides additional protection for demanding conditions and stop-start mountain activity.
