Arc'teryx Atom SL Women's Insulated Hoody

The Arc'teryx Atom SL Hoody is the lightest and most packable insulated hoody in the Atom line, built for high-output efforts in cold, wet conditions. Its Fortius™ Air 20 face fabric balances air permeability with weather resistance, while 100% recycled stretch synthetic insulation in the core delivers focused warmth without restricting movement.

Uninsulated, mesh-lined sleeves and stretchy Octa® Fleece side panels regulate temperature and improve ventilation, making it easy to wear as a standalone layer or under a waterproof shell. An adjustable StormHood™, drawcord hem, and two zippered hand pockets round out the design, and the FC0 DWR finish repels light moisture without intentionally added PFAS.

Lightest, versatile synthetically insulated hoody

Atom SL Hoody Women's

Lighter than the original, the Atom SL Hoody is a useful and packable piece. Wear it as a standalone layer during cold, wet weather or layer it with a waterproof shell for additional warmth and mobility. Breathable and weather-resistant, it has stretch insulation in the body but not the sleeves or hood, maximizing packability while delivering focused warmth to the core.

Sizing & fit

Fit & Sizing

Fit: Fitted

The trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over first layers or under outer layers.

Compatibility

Designed to layer comfortably over first layers or under outer layers thanks to its fitted, low-profile cut. Pairs well with a waterproof shell for added protection in wet conditions.

How to use

Wear the Atom SL Hoody as a standalone layer for trail runs and high-output activities in cold, wet weather, or layer it under a waterproof shell when mountain pursuits demand additional warmth and mobility. The fitted, articulated patterning supports freedom of movement, while the adjustable StormHood™ and drawcord hem seal out drafts.
