Arc'teryx Atom Vest Men's

Conquer the unpredictable with the Arc'teryx Atom Vest Men's, your core's new best friend when temperatures drop on long ascents. This lightweight marvel (weighing just 195g) delivers reliable warmth even when moisture creeps in, thanks to the premium Coreloft™ Stretch synthetic insulation that outperforms down in damp conditions. The ingenious design combines insulated front and back panels with stretchy Octa® Fleece side panels, giving you unrestricted mobility while scrambling up rocky sections or reaching for that next climbing hold.

Whether you're hiking through shoulder-season mist or layering up for winter objectives, this versatile vest adapts to your adventure. The recycled nylon shell with PFAS-free DWR treatment shrugs off light precipitation while hidden-zipper hand pockets secure your essentials without compromising the vest's clean aesthetic. Slip it on as a standalone piece when the morning chill bites or layer it under your shell when the weather turns—either way, the Atom Vest delivers the perfect balance of warmth, movement, and packability that high-output activities demand year-round.
