Arcteryx Atom Vest

The Arc’teryx Atom Vest takes one of the brand’s most useful insulated layers and makes it even easier to work into your rotation.

Coreloft synthetic insulation adds lightweight warmth through your core and continues to perform when damp, while stretch side panels improve mobility and help manage heat when you’re moving. The outer fabric adds wind resistance and an FC0 DWR finish for light weather protection.

It’s especially useful under a ski shell when you want a little extra warmth without adding bulk through your arms, but it works just as well hiking, traveling, or worn on its own around town. Simple, packable, and useful across a pretty wide range of temperatures.
