The Kor Alloy™ Jacket is built to keep you in the comfort zone with a smart blend of materials: a Pertex® Quantum Air shell for wind resistance and breathability, plus a strategically mapped mix of AirMesh™ lining and Primaloft® Gold Active insulation for targeted warmth. This layer off-loads excess body heat and moisture on the ascent and effectively insulates under your favorite shell on the descent — making it a go-to midlayer for high-output backcountry missions.
