Taking its trust in wool outside of the limits of a baselayer, Ortovox implements wool in some way or another into every one of its garments. The Piz Bianco Insulated Jacket utilizes the temperature regulating benefits of Swiss wool in an insulating layer that can be worn on its own or under a shell. The Swiss Virgin wool insulation helps regulate your body temperature while transporting moisture away from your body, making it ideal for high aerobic activities in cold and high environments commonplace to ski mountaineering and alpine touring. The nylon micro ripstop fabric readily resists tearing, and is fitted with a water resistant membrane to protect from moisture. Its ergonomic fit helps to insulate and allows you wear a shell over this jacket when the weather turns foul.
