Product Details

A perennial staple for all climbers, the Atom Hoody provides lightweight, durable warmth. A versatile jacket that can be adapted within a layering system, Coreloft™ synthetic insulation is strategically placed at the chest and back for thermal efficiency. Highly compressible and warm when wet, the insulation retains loft, even after repeated packing and unpacking. Stretch side panels deliver full mobility and enhance ventilation. When worn as an outer layer, Tyono™ 20 air-permeable fabric helps to regulate airflow, ensuring wind resistance and repelling excess moisture. An insulated StormHood™ offers additional warmth and stretch-knit cuffs help to lock out drafts. With zip secure hand and chest pockets for small essentials, this hoody will accompany you on your adventures for years to come.
