Arc'teryx Atom SL Hoody Women's

The Arc'teryx Atom SL Hoody delivers precisely what active women need when the mountains serve up cold, wet conditions and demanding terrain. This packable insulation layer strategically places Coreloft™ Stretch insulation only in your core while leaving arms uninsulated with mesh lining, preventing overheating during high-output trail runs and alpine climbs while keeping your torso warm when you need it most. The stretch Fortius™ Air 20 face fabric moves with you through technical terrain, while breathable Octa® fleece side panels enhance ventilation exactly where you generate the most heat. Whether you're pushing pace on a chilly morning run or layering under a shell for serious mountain pursuits, this fitted women's insulated jacket compresses down small enough to disappear in your pack until conditions change. It's the kind of versatile mid-layer that transforms from essential trail running gear to reliable alpine climbing insulation, making it one of those pieces you'll reach for again and again when the weather gets interesting.
