The Merino 105 Long Sleeve by Ortovox impresses with its particularly athletic cut. Long sleeves and a classic round neckline complete the design. Made of high-quality merino wool, the long-sleeve comes with temperature and moisture regulating properties. At the same time, the material is odor-neutralizing and feels really soft on the skin.
