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. 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.
