Arc’teryx designs are careful and intentional, and the Thorium’s elevated performance comes from focused construction and patterning. The women’s specific Regular fit is streamlined and layers easily under a hardshell in cold conditions. Articulation built into the sleeves and gussets under the arm provide a level of freedom of movement not often found in an insulated jacket. Because the Thorium AR is intended as a midlayer, Arc’teryx is able to use sewn through construction to further reduce weight and increase packability.


Arc’teryx Down Composite Mapping technology combines the goose down insulation with panels of Coreloft™ synthetic insulation in areas prone to moisture. Used in the hood, cuffs and under the arms, the Coreloft™ insulates even if wet. Down is used in the sleeves and around the body’s core. The insulated StormHood™ fits close to the head for efficient thermal performance and a high level of visibility, and two zippered pockets secure small essentials.
