Product details

Steeped in the alpine, this versatile hoody has warmed climbers, hikers, backcountry skiers and downtown commuters. Worn as a midlayer or standalone, it performs across a range of conditions and output levels. Coreloft™ Compact insulation retains warmth even if wet and has loft retention that withstands years of packing and unpacking. The water resistant Tyono™ 20 face fabric is soft, breathable and durable, stretch side panels improve ventilation and freedom, and the insulated StormHood™ adds warmth.

Updated with a revised fit.

The Atom Hoody was previously the Atom LT Hoody.
