The Arc’teryx Atom SV Hoody for women is the warmest jacket in the Atom series, built for cold alpine environments and demanding ascents. Thermo-mapped Coreloft™ insulation combines 120 g/m² in the body with 60 g/m² under the arms to balance warmth and breathability during exertion. The mini-ripstop nylon shell with Pfas-free DWR finish is breathable, lightweight, and wind resistant, while the insulated, helmet-compatible StormHood™ provides added protection. With internal cuff gaiters, an adjustable hem, and regular fit, it works as a standalone or layered under a hardshell.
