Whether used as a midlayer or on its own, the Arc'teryx Atom Vest is highly versatile for all seasons, terrains, and physical activities. Thanks to its top-notch insulation, materials, and design, this newest iteration continues to deliver legendary performance.

Additionally, the stretch fleece side panels promote breathability and mobility, and the entire vest can be conveniently packed into its own pocket.
