The Summit Chamlang Softshell trousers deliver all-day comfort during challenging alpine conditions. When the mountain wind picks up and threatens to cause a chill, WindWall™ technology protects you from the elements. And you won't be held back on the climb, as four-way stretch and articulated knees offer full flexibility to help you make the toughest reachy moves. Kickpatches stand up to brushes with rock and other pointy mountain tools, while versatile cuff openings provide a seamless fit with a variety of mountaineering boots. Summit Series™ layers all work together for optimum performance in terms of breathability, insulation, weather resistance and moisture management.
