Arc'teryx Atom Women's Insulated Vest

The Arc'teryx Atom Vest for women is a synthetic-insulated midlayer built for high-output days in cold conditions. Its Coreloft 60 insulation is 100% polyester and continues to insulate when damp, making it a dependable alternative to down when you are moving fast and working up a sweat.

The body is a 20dx20d nylon ripstop with an FC0 DWR finish, while the lining is 20D recycled dope-dyed nylon ripstop and the contrast panels are circular knit fleece with elastane for stretch. The vest is lightweight, wind resistant, breathable and packable, so it layers easily under a shell or packs away when the temperature rises.
