"What Our Gearhead® Experts Are Saying:""This jacket has become my alpine layer of choice. The mapped insulation and breathable panels keep me from overheating on the skintrack, and it still blocks wind like a champ when I reach the ridgeline. It’s a sweet balance between warmth, weight, and mobility.""For fast-paced pursuits in unpredictable weather, the Kor Alloy Jacket keeps us protected and moving with intention. Mountain Hardwear pairs Pertex® Quantum Air with mapped AirMesh™ panels and PrimaLoft® Gold Active insulation to strike an ideal balance of warmth and airflow. The result? A piece that adapts to our output, whether we’re chasing vertical on skis or scrambling under granite overhangs. Every detail is built for performance without excess—from the lightweight stretch-woven fabric to strategically placed underarm vents. Secure hand pockets, a zippered chest pocket, and reflective MHW branding round out the features. This is the jacket we count on when our days demand both speed and versatility."
