Arc'teryx Men's Atom Vest - Winter 2026/2027

Performs-even-when-wet core warmth for hiking, climbing, touring, and living in. If you want the warmth of an Atom Hoody with a wider range of motion and smaller footprint, you&';re 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. The Coreloft synthetic insulation stays warm even if you run into light weather, making it a better alternative to down for high-output days year round.
