This jacket is made for days in the mountains that begin and end by headlamp. Its extraordinary breathability reduces the need for constant rest stops to adjust layering. We use a tough 5.2-oz. stretch-woven nylon shell that's windproof and water resistant, yet lightweight and highly compressible. Inside, built -in R2 polyester insulates the torso and speeds moisture away from the skin. Lighterweight R1 inside the arms and low-profile water-resistant zippers help keep you limber. Two handwarmer pockets are accessible above a hip belt; a stash pocket holds small essentials. The insulated hood fits over a helmet. A drop tail, drawcord hem and removable between-the-Iegs strap seal out even the lightest powder on the biggest day. Imported.
