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 FC0 DWR finish for a lower footprint.
