Strong, robust and sustainable cooling: The durable yarn and natural cooling effect of Tencel™ make our 150 MERINO COOL line for women ideal for hot summer days in the mountains. BETA-SPUN technology gives our 150 COOL LOGO LONGSLEEVE the required stability: In this intricate spinning process, fine polyamide filaments are spun around a merino wool and Tencel™ core. 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 Tencel™ fibers ensures great evaporative coolness. The 150 COOL LOGO LONGSLEEVE for women is therefore the perfect companion on warm summer days.
