Arcteryx Proton Hybrid Hoody Women's


The backcountry demands balance – insulation to offset the cold, air permeability to prevent overheating, protection from wind, and freedom to move across demanding terrain. Combining all of these elements, the Proton Hybrid delivers optimal thermal comfort and the freedom of stretch – uptrack to descent. Coreloft™ Compact insulates, the Fortius™ Air 50 outer allows airflow, and GORE-TEX INFINIUM™ at the yoke and hood blocks wind and light weather. This is an essential addition to your backcountry kit.
