We rely on Arc'teryx's high-tech creations for backcountry adventures year-round. In the coldest months of the year, the Thorium AR Hooded Down Jacket offers the versatility we need to seek out powder stashes and stay warm in the city. Taking the best qualities from both down and synthetic insulation, this multifunctional midlayer stays warm and lofty, even when heavy snow pushes past the tough Arato nylon fabric. The appeal of this versatile jacket is apparent for anyone who can't stop exploring when the temperatures drop, so we're grateful to have this style stashed for extra heat under a shell and fashionable comfort on casual downtown adventures.
