Stop-and-go activities, such as ski mountaineering, alpine mountaineering or climbing are all about climate control. Periods of intense physical activity are often followed by static periods where you risk overcooling. Salewa's thermo-regulating Ortles Hybrid TirolWool Celliant Jacket is designed to meet the specific insulation needs of different areas of the body during high-octane activities in cold conditions, while its tough Durastretch inserts make it ideal for rugged alpine use.
