Arc'teryx Men's Atom Vest Black size:M Shell and liningX000009559 002291 If you want the warmth of an Atom Hoody with a wider range of motion and smaller footprint, youre in the right place. Pull on the Atom Vest when you feel the temperature dropping on longer hikes and climbs or wear it as a midlayer under a shell for touring and wet winter objectives.
