Arc'teryx Atom SL Men's Insulated Hoody

The Arc'teryx Atom SL Hoody is a lightweight, packable insulated layer for men, built with a Fortius™ Air 20 plain weave body and a recycled 20d nylon lining, both finished with an FC0 DWR that sheds light moisture. Coreloft™ Stretch synthetic insulation (40 gsm) is placed in the body only, not the sleeves or hood, so warmth stays focused on the core while the jacket stays highly compressible.

Octa® polyester fleece side panels add breathability, and the fitted silhouette keeps bulk low for layering under a waterproof shell or wearing alone on high-output days. The lined StormHood™ cinches down and the jacket can be packed into its own hood for compact storage.
