Arc'teryx Men's Thorium AR Down Hoodie is exceptionally versatile, hardwearing and warm, and performs as a cold weather mid-layer or as a standalone. The Thorium's regular fit is streamlined and layers easily under a hardshell in cold conditions, perfect for snowboarding or skiing. Enjoy the lofty 750 fill European grey goose down that gives incredible warmth for little weight, is durably resilient, and packs easily. The outer is updated with durable and subtly textured Arato™ 30 nylon. This hoodie's lightweight material withstands abrasion, packs compactly and has a DWR finish to repel moisture. Arc'teryx's Down Composite Mapping™ technology combines the goose down insulation with panels of Coreloft™ synthetic insulation in the hood, cuffs and under the arms, areas prone to moisture and used in the sleeves and around the body's core, ensuring you stay warm and dry all day long. Additionally, the Thorium hoodie is equipped with a synthetically insulated Stormhood™, two zippered pockets to secure your small essentials and an internal zipper pocket with a stuff sack. The Arc'teryx Men's Thorium AR Down Hoodie is designed to use in true alpine conditions.
