Flying across technical terrain – the ultimate mountain-running experience doesn’t exist if your kit weighs you down. Our lightest, most air-permeable mountain running hoody protects you on exposed trails and prepares you for shifting conditions. Its Canim ripstop fabric resists wind and moisture, Permair 20 panels ventilate, a streamlined adjustable hood extends protection, and – packed into its pocket – it travels virtually unnoticed. Until you need it.
