Arc'teryx Atom SL Hoody W women's insulated jacket

The Atom SL Hoody jacket from Arc'teryx is an ultralight and extraordinarily compressible technical women's jacket, ideal for those seeking targeted warmth without sacrificing maximum breathability during trail running or fast hiking. Compared to the classic version, this "Superlight" model weighs only 240 grams and focuses on torso protection thanks to a recycled stretch synthetic insulation placed exclusively on the body, leaving the sleeves and hood uninsulated to optimize thermal management. The Fortius™ Air 20 outer fabric, now made with recycled materials, perfectly balances air permeability with wind and weather resistance, supported by a PFAS-free FC0 DWR water-repellent treatment. The new Octa® fleece side panels significantly improve ventilation and freedom of movement while reducing the release of microfibers into the environment. Featuring a slim fit with articulated elbows and reinforced armpits, the jacket has mesh-lined sleeves for lightweight protection and an adjustable StormHood™ with a slim profile, now lined for added comfort. The technical features are completed by an adjustable hem with a drawcord to seal in warmth, two zippered hand pockets, and Polygiene odor control treatment, making it an extremely versatile piece both as an outer layer on cool days and as a midlayer under a waterproof shell. Made according to strict bluesign standards, the Atom SL Hoody is the perfect choice for intense outdoor activities where every gram counts and sweat management is essential.
