Our 150 Merino Cool line combines the perfect properties for intensive Tours: Soft Merino Wool regulates temperature, while Tencel™ lyocell wood fibers sourced from responsibly managed forests efficiently absorb moisture – for a naturally Dry feeling on the Skin and fewer unpleasant odors. The quick-drying shirts are also more robust thanks to the Betaspun® spinning technology, a process in which the fibers are wrapped with polyamide filaments.
