Arc'teryx Atom Mens Jacket 2026

Warm-even-when-wet jacket you can hike, climb, tour, and live in.

Description

Everything you love about the Atom Hoody (minus the hood), the Atom Jacket is the layer you can count on to see you through multiple high-output activities. Wear it solo for chilly forest hikes with windy summits, climbing at the crag and hanging at the campsite, or as a midlayer for touring and wet winter objectives. The Coreloft synthetic insulation stays warm even if you run into light weather, making it a better alternative to down for high-output days year round.

What's been updated: Updated with a FC0 DWR finish for a lower footprint.
