Arc'teryx Atom

The Arc'teryx Atom vest delivers lightweight warmth and unrestricted movement for hiking, climbing and cold-weather touring. Its synthetic Coreloft insulation continues to provide warmth when damp, making it a dependable choice for humid conditions and high-output activities.

Designed as a versatile midlayer, it packs down small and integrates easily beneath an outer jacket. The adjustable hem helps refine the fit, while the regular cut suits active layering and everyday outdoor use.
