Salewa Woman's Vest Ortles Hybrid TWR is the ideal vest for mountaineering and multi-activity outdoor. Designed to help you regulate your core body temperature and prevent overcooling during intense physical activity in cold conditions. The latest iteration of our well-known Ortles Hybrid TirolWool® Responsive Vest is the ideal extra insulation layer for all alpine activities. TirolWool® Responsive is our proprietary lightweight insulation material that combines wool sourced from Tirolean sheep with innovative polyester fibres enhanced with thermo-reactive minerals. Heat emitted by the body is absorbed and converted into infrared radiation, which is stored and reflected back to the body – keeping you warmer for longer. TirolWool® Responsive is water-resistant, breathable and will still keep you warm when wet. Further features include: warm Durastretch inserts with 22% wool content for ease of movement, an integrated pack-it pocket, a high ergonomically-shaped front collar, and front zip with full-length internal windproof flap.
