Arc'teryx Atom Women's Insulated Jacket

The Arc'teryx Atom Jacket for women is a breathable, hybrid-insulated midlayer built for all-mountain activities. Coreloft 60 synthetic insulation traps warmth and keeps working even when damp, while stretchy circular knit fleece side panels dump excess heat on the move. The 20D nylon ripstop body and lining are treated with a PFC-free DWR finish for light weather resistance.

Wear it as a standalone piece on cool days or slide it under a hardshell for a versatile layering system that stays warm in wet conditions. The fitted cut and lightweight construction make it easy to pack and carry, whether you are climbing, skiing, or hiking.
