Ortovox 150 COOL LOGO TS W

The 150 Cool Logo TS W from Ortovox is a functional, sustainably cooling basic shirt made from 150 Merino Cool fabric. The secret to its cooling effect lies in the blend of two natural fibers: merino wool and Tencel. Tencel is a fiber derived from eucalyptus wood, characterized by high fiber moisture, significant evaporative cooling, and a smooth fiber surface. As a result, it cools your skin without the need for any added chemicals. At the same time, Tencel products are particularly durable. The material mix is made robust and high-performing through an elaborate spinning process: the Beta-Spun technology refers to a manufacturing method in which fine polyamide filaments are spun around the merino wool and Tencel. The protective polyamide sheath makes the fabric extremely abrasion-resistant and robust—without losing the benefits of merino fibers and the cooling Tencel fiber. Additionally, the 150 Cool Logo TS is highly breathable and quick-drying. Thanks to its odor-reducing properties, you can wear this outdoor shirt for several days in a row between washes without any issues. In short, it’s a perfect first layer—functional, natural, and sustainably cooling—ideal for mountaineering, climbing, or other outdoor activities on hot days.
