Protection and breathability: the two opposites come together in the UYN CORESHELL jacket, providing the cross-country skier with perfect thermal comfort. The front, with the exclusive MEMBRAIN115 membrane and BUFFERCONE insulation technology in the inner layer, keeps the body warm, protected from water and wind. When activity is maximal, the moisture produced by the body is free to escape through the micro-perforated panel on the back. To achieve an optimal comfort experience, UYN engineers developed ERGOMOTION technology: the one-piece construction of the shoulder and sleeve eliminates creases and constrictions. The highly elastic 3D knitted fabric allows the garment to adapt naturally to the movement of the arms ensuring maximum agility.
