The Atom SL Hoody combines lightweight insulation with exceptional versatility for mountain pursuits. Its strategically placed core warmth works solo on cool, damp days or layers effortlessly under a shell for added protection. Breathable, weather-resistant fabric sheds moisture while maintaining packability, making it perfect for alpine climbers and trail runners seeking minimal weight without sacrificing performance. The streamlined hood and fitted sleeves compress easily into your pack.
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.
