Ortovox 140 Cool MTN Playground Shirt - Sustainability is a top priority for the 140 Cool line, because it consists of 100% natural fibers with the best properties for movement-intensive sports on hot days. Fine Tasmanian merino wool is pleasantly soft, naturally moisture-regulating and neutralizes unpleasant odours, while the cellulose fiber Tencel Lyocell has a cooling effect with its smooth surface and high evaporation coolness. The shirts of the 140 Cool line are light and particularly comfortable to wear, but still robust for use in alpine terrain. Thanks to its sporty cut and casual print, the 140 Cool line always cuts a fine figure, whether on the mountain or in the valley.
