Arc'teryx Norvan Insulated Hoody

The Arc'teryx Norvan Insulated Hoody is a lightweight, packable synthetic-insulated piece built for high-output cold-weather trail running. Its Fortius Air 20 face fabric balances airflow with wind resistance, and a PFAS-free DWR finish sheds light moisture. Mapped 25gsm Coreloft insulation warms the front, sides, and sleeves while keeping weight and bulk remarkably low.

Every detail supports moving fast on the trails: a fitted, articulated cut allows a natural stride, while uninsulated underarm gussets and a back panel increase ventilation when effort rises. The low-profile hood rolls away into the collar, integrated flip-mitts keep hands warm without extra layers, and reflective elements improve visibility in low light. A zippered side pocket doubles as a stuff sack, making the hoody easy to pack for runs in changing mountain conditions.
