The men's version of the 120 Tec Mountain T-Shirt M from Ortovox may be high-tech, but it is made largely from a renewable raw material: virgin wool from Tasmanian sheep. The fine wool (17.5 microns) is spun around a core of polyamide filaments. This retains all the practical properties of wool - anti-odour, moisture and temperature-regulating, skin-soft - but the fabric is lighter and more durable. The shirt does not itch or scratch the skin, has a figure-hugging cut, features a mountain print and small logo print and is easy to care for.
