Description
Lighter than the original, the Atom SL Hoody is one of the most useful (and packable) pieces you can own. Wear it as a standalone layer when trail runs take you through cold, wet weather or layer it with a waterproof shell when mountain pursuits demand additional warmth and mobility. Breathable and weather-resistant, it has stretch insulation in the body but not the sleeves or hood — maximizing packability while still delivering focused warmth to your core.
What's been updated: Updated with recycled Fortius™ Air 20 fabric, recycled stretch synthetic insulation, and FC0 DWR finish for improved mobility and a lower Footprint USA. New Octa® Fleece side panels give enhanced breathability and less micro shedding. The StormHood™ is now lined and no longer stowable. The Bird logo is embroidered for long lasting visual.

NOTE: Men's fit has been updated with a revised fit. Medium size remains unchanged. Smaller sizes are now tighter and larger sizes are now looser. Arc'teryx sizes are intended to fit the above body measurements. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
Fit & Sizing
Fit: Fitted
Our 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.
