Arc’teryx’s Atom Hoody is the mountain‑town multitasker — warm enough for cold trail mornings, breathable enough for fast climbs, and slim enough to run as a midlayer when winter gets serious. Coreloft™ Compact 60 insulation keeps heat even when damp, while Tyono™ 20 fabric adds light wind protection without killing airflow. Stretch fleece panels boost ventilation, and the soft recycled liner stays comfortable against the skin. A reliable, moisture-resistant year‑round layer built for real movement outdoors.
