Arc'teryx Atom Men's Insulated Vest

The Arc'teryx Atom Men's Vest is a lightweight, packable synthetic-insulated layer built for hiking and climbing. Coreloft™ Stretch insulation in the body retains warmth even in light weather, while Octa® Fleece side panels add ventilation and freedom of movement.

The Fortius™ Air 20 nylon face fabric is breathable and finished with an FC0 DWR that repels moisture without intentionally added PFAS. Two hidden zippered hand pockets, an adjustable drawcord hem and ergonomic patterning keep it practical as a standalone piece or a midlayer under a shell.
