When high-alpine adventures are in your future, look no further than the Arc'teryx Men's Atom AR Insulated Jacket. The DWR treatment lets this piece work as a standalone layer when things are really cold, shedding small amounts of moisture as well as keeping the abrasion-resistance as tough as possible. The athletic cut of the Atom lets it be used as a midlayer insulating piece as well, since things can't always be as dry as you'd like. Coreloft insulation throughout the jacket delivers plenty of insulation for your next summit bid. Arc'teryx distributed the insulation heavier throughout the body and lighter through the arms since, as the old maxim goes, keep the core warm, and the limbs will follow. Zippered pockets for your hands, and one for your media, lets you keep your valuables and necessities at easy reach.
