Thermal underwear
To cope with the cold during your winter sports activities, it's essential to equip yourself with a few essentials, namely thermal ski underwear. For the upper body, long sleeves are available, with a zip collar or high turtleneck. Thin but warm, they'll feel like a second skin and give you a pleasant sensation of warmth. Thermal underwear is the first layer in the three-layer approach. They offer a perfect balance between warmth and breathability, whatever the model chosen. Underwear bottoms take the form of sports pants or leggings, depending on your preference. Whatever the outside temperature, you can be sure of effective protection against the cold thanks to our wide range of underwear. What's more, our wide range of models ensures unquestionable comfort, as well as a vast choice of colors for your cross-country skiing outings. Whether you're a man, a woman, a girl or a boy... the whole family is sure to stay warm this winter thanks to DECATHLON.
