Those moments when you’re just gliding across technical terrain – flying. The experience doesn’t exist if your kit weighs you down.

Arc'teryx's lightest, most air-permeable mountain running hoodie 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.
