Made for high-output ski mountaineering missions, our L4 Proprius Soft Shell Trousers are lightweight, durable, and supportive. Four-way stretch fabric and articulated knees provide exceptional range of motion as you climb to the summit and carve your way back down, while WindWall™ technology protects you from howling wind as you go. Side zips featuring a stretch-panel gusset and dual-snap ankle closure make it easy to use ski-touring boots. For added durability, there are Keprotec®- reinforced kick patches to deflect your crampons. Part of the Summit Series™ collection - the world’s finest alpine equipment.



Stretch fabric provides greater range of motion and ultimate comfort.
