Arc’teryx designs for use in true alpine conditions. This requires an elevated performance that comes from careful design and patterning. The Thorium’s Athletic 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. This ergonomic freedom is an Arc’teryx design commitment that infuses every piece they make. 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 collar, cuffs and under the arms, the Coreloft™ insulates even if wet. Down is used in the sleeves and around the body’s core. The Thorium’s tall collar seals out drafts, and two zippered pockets secure small essentials.
As an alternative to down fill insulation, we also offer synthetic fill products, such as the Atom AR Jacket.
