Functional underwear is an essential part of sports equipment. Winter, summer or compression clothing made of merino wool or synthetic material will help you feel good in every situation. Functional underwear doesn't absorb water, so sweat can evaporate faster. This also cools the surface of the skin or, on the contrary, retains heat and reduces the external temperature of the skin. Summer functional underwear can be used for running, cycling and other outdoor sports, while thermal clothing such as T-shirts, trousers, underwear and socks can be used for winter sports. All of these functional underwear (521 types) are in stock on our e-shop or in our stores. But your purchase doesn't have to end there. See also other products from the Functional Base Layers category or contact our customer support.
