Backcountry travel is not linear - it involves uptracks, traverses, transitions, and descents. As temperatures and conditions shift, staying comfortable is crucial. That's where the Proton Hybrid comes in - with its Coreloft™ Compact insulation and Fortius Air 50 outer, it balances warmth, airflow, and vapor transfer. Additionally, the yoke and hood feature GORE-TEX INFINIUM™ for zonal windproof protection and defense against light snow and sleet. Versatile and comfortable, this is the ultimate backcountry essential.
