The Mountain Hardwear Kor Alloy is a men's synthetic-insulated jacket built for active use in cold, wet conditions. PrimaLoft Gold Active insulation is thin, stretchy and keeps warmth when damp, and the jacket packs down small. It has no hood and a hip-length cut, so it layers under a shell or works alone on dry, cool days. Rivals like the Patagonia Nano-Air and Arc'teryx Atom LT offer similar breathable synthetic warmth, but the Kor Alloy leans toward minimal weight and packability over weather protection.
