Atom jacket

Lightweight, packable, and proven, the Atom—an Arc'teryx icon—is a performance warming layer for backcountry adventures, alpine climbs, and urban commutes. Refined for its next generation, we've elevated its performance and expanded its versatility. Coreloft™ Compact 60 insulation retains warmth when wet and stands up to repeated packing and unpacking. The soft, durable Tyono™ 20 face fabric resists wind and weather, and stretch fleece side panels enhance ventilation and range of motion.
