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 Arc'teryx Proton Hybrid Hoody delivers optimal thermal comfort and the freedom of stretch – from 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.

Size and Fit Tips: 

Fitted Fit - This trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over our first layers. Be sure to double-check our new sizing charts before checkout.
