Men's Atom Vest

The ATOM VEST delivers core warmth with greater freedom of movement and a smaller pack size than the Atom Hoody. Ideal as an outer layer on cool hikes and climbs or as a midlayer under a shell, it uses Coreloft™ synthetic insulation that stays warm even when damp—making it a versatile choice for high-output activities year-round. Updated with FC0 materials, a PFAS-free DWR finish, and 100% recycled stretch insulation for improved mobility. Finished with an embroidered Bird logo for lasting detail.
