Arc'teryx Thorium Womens Hoody 2026

A proven hoody for cold, dry conditions, the Thorium delivers serious warmth and handles a wide range of environments. Packed with 750 fill-power Responsible Down Standard certified grey goose down, it offers outstanding thermal performance for its weight. Down Composite Mapping™ strategically places Coreloft™ synthetic insulation in areas prone to moisture. The light, durable Arato™ 30 nylon shell has a DWR treatment for water repellency, the liner ‘s bio-derived material reduces petroleum use, and the insulated adjustable hood fits over a helmet.

Size and fit tips: The Thorium Hoody has a roomier fit in the body and a longer length than its predecessor, the Thorium AR.
