Our medium-weight cardigan made of 100% yak wool is a super-warm mid layer that reliably keeps you warm on the coldest winter days. Despite its insulating properties, it wicks away excess heat and moisture, helping you avoid overheating and stay dry during strenuous ascents or fast-paced hikes. An extra-high stand-up collar and thumb loops add warmth around the neck and hands, ensuring uncompromising performance in winter and high-alpine conditions. This midweight cardigan is perfect as a mid layer for the coldest winter days in the high mountains and is ideal for mountaineering and ski touring. Thanks to its full-length zipper and extra-high collar, you can also wear it as an outer jacket from spring through fall on mountaineering and trekking trips.
