Arc'teryx Atom Womens Hoody 2026

The Atom Hoody is the solution to your “which jacket should I wear?” problem. 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 new FC0 material; the side panels and lining are now made with a recycled material as well. Updated fit, with a slightly wider collar and roomier sleeve opening, for improved mobility and layering.
