Temperatures well below freezing magnify the challenge of staying comfortable when you’re exerting hard for many hours in the backcountry, in activities like backcountry skiing and climbing. You sweat hard going uphill and get wet; then you lower your exertion level on gentler terrain, or to ski downhill or belay, and you get cold because you’re still wet. What’s needed is a winter jacket that delivers good warmth and protection from wind and flying snow, yet breathes so well that your base layer dries out before you get cold. Enter the Jammu Jacket.
