Uptracks and traverses, transitions and descents – backcountry snow travel is not linear. Output, temperatures, and conditions shift, and you need to stay comfortable through it all. Created to meet these realities, the Proton Hybrid’s Coreloft™ Compact insulation and Fortius Air 50 outer balance warmth, airflow, and vapor transfer. GORE-TEX INFINIUM™ at the yoke and hood delivers zonal windproof protection and helps shed light snow and sleet. Versatile, comfortable – this is a go-to backcountry piece.
