Arc'teryx Men's Atom SV Hoody in Black Sapphire

When warmth is your priority, zip up the Atom SV Hoody. Made for frigid hikes and above-the-treeline adventures, its synthetic insulation and StormHood™ seal in heat for consistent comfort in cold, damp, and windy conditions. Strategically placed for max breathability, full-length side panels provide a welcome flow of air on that final summit stretch. The workhorse in your winter kit, it delivers hefty protection on its own and rides comfortably under a hardshell when the sky opens up.

What's been updated: Updated with a more streamlined fit and a FC0 DWR (Durable Water Repellent) finish that’s free from intentionally added PFAS. Improved male-specific thermal patterning on the side panels maximizes breathability and reduces overheating.

Arc'teryx Layering Guide

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
