Stop-and-go activities such as ski touring, mountaineering and climbing are all about climate control. Periods of intense physical activity are often followed by static periods where there is a risk of overcooling. Our thermoregulating Ortles Hybrid TirolWool® Responsive Jacket is designed to meet the specific insulation needs of different areas of the body during activities in cold conditions, and its durable Durastretch inserts make it ideal for demanding climbing applications. Hybrid design meets hybrid insulation - TirolWool® Responsive is our proprietary lightweight insulating material that combines innovative polyester fibers enriched with thermoreactive minerals and wool sourced from Tyrolean sheep. The heat emitted by the body is absorbed and converted into infrared radiation, which is stored and reflected back to the body - keeping you warm for longer. TirolWool® Responsive is waterproof, breathable and keeps you warm even when wet. The fitted, adjustable at the back, insulated hood provides additional protection. Thanks to its small size, the jacket fits easily into any backpack and fits under any hardshell.
