A cool ridge breeze should not force a full wardrobe change. The Women's Atom Vest adds resilient Coreloft™ warmth through the torso while stretchy side panels vent excess heat and preserve freedom of movement. Its wind-resistant shell layers neatly on top of a base layer for hiking or beneath ski outerwear when winter arrives. This lightweight Arc'teryx insulated vest earns year-round mileage through climbing, touring, travel, and active daily wear.
