Gamma MX Hoodie

Stay light, stay warm: The Atom Vest by Arc'teryx® does it all. Featuring Coreloft™ insulation, it's lightweight, breathable, and warm-even when wet-while resisting compression over time. The Tyono™ 20 face fabric offers wind protection and breathability with a PFAS-free DWR finish for water repellency. Durable stretch fleece panels enhance mobility, and the hybrid mapping technology places fabrics where you need them most. A mid-height collar traps warmth, while zippered hand and chest pockets secure essentials. Compact and packable, this vest stows into its own pocket and clips to a carabiner. Adventure-ready, layer-friendly, and eco-conscious, it's built for those who demand more.
