The 150 COOL MOUNTAIN FACE T-SHIRT for men is ideal for long, intense spring ski tours thanks to its durable yarn and the naturally cooling effect of the TencelTM Lyocell fibers. BETA-SPUN technology gives our shirt the required stability: This protective polyamide sheathing makes the fabric more scuff and tear resistant. Fine merino fibers simultaneously offer unique comfort and provide an optimum body climate, while the smooth surface of TencelTM fibers ensures great evaporative coolness when things get hot. With its sporty cut, cool colors and understated print, the 150 COOL MOUNTAIN FACE T-SHIRT for men always looks great too. 150 MERINO COOL In the 150 MERINO COOL line, ORTOVOX combines TencelTM fibers, sourced from sustainable forestry, with merino wool. The wood fibers are characterized by great evaporative coolness and flat fiber surface - ensuring it cools automatically. An intricate spinning process makes the material mix robust and extremely functional. BETA-SPUN technology refers to a manufacturing process where fine polyamide fibers are spun around merino wool and TencelTM. The protective polyamide sheathing means the fabric is exceptionally scuff-resistant and robust - without sacrificing the benefits of merino fibers or the cooling TencelTM fibers. ORTOVOX WOOL PROMISE (OWP) Merino wool has been an integral component of ORTOVOX\'s mountainwear since 1995. The focus of this has always been the protection of people, animals and nature: Our merino wool comes from selected farms that comply with our own wool standard: the ORTOVOX WOOL PROMISE. These farms are regularly monitored within the framework of the OWP to ensure that the highest standards of animal welfare are maintained. The OWP is our commitment to fair wool.
