Detailed Description
The Atom SV Hoody is the warmest jacket in Arc’teryx’s Atom family, made for frigid hikes and days above the treeline. Coreloft™ synthetic insulation and an insulated StormHood™ hold in heat through cold, damp and windy conditions, while full-length stretch side panels let excess heat escape on the final push to the summit. It’s protective enough to wear on its own and rides comfortably under a hardshell when the weather turns. Formerly the Atom Heavyweight Hoody.
