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.
