The Sportful Winter Tee Halfzip redefines how a technical base layer performs in cold conditions. Designed for dedicated cross-country skiers, it combines the warmth of our signature ribbed fabric with the versatility of a high collar and a half-length zip, allowing you to precisely regulate temperature during every effort. Its ribbed thermal structure creates air channels that retain body heat close to the skin, generating natural insulation without compromising breathability. This means you stay warm while moisture and excess heat are effectively managed — even during the most demanding climbs or intervals. The stretch polyester composition ensures an ergonomic, body-hugging fit that moves seamlessly with your body. The quarter-length zipper provides instant ventilation when the pace rises, while the high collar offers added protection when the temperature drops. Minimal seams and a soft handfeel make this base layer exceptionally comfortable under any outer layer, from race suits to technical jackets. Built for athletes who know that performance starts from the first layer, the Winter Tee Halfzip is ideal for those who push hard through the cold but never compromise on comfort. Born from the Dolomites, tested on snow, trusted by athletes. Sportful Winter Tee Halfzip — performance starts from within.
