The JAY-PI functional shirt is a high-quality ski undershirt specifically designed for winter sports. It offers an optimal combination of functionality and comfort to meet the demands of active athletes. The shirt is made from an innovative FLEXNAMIC® material, known for its high elasticity and breathability. This ensures excellent freedom of movement and a comfortable wearing experience, even during intense activities. The long-sleeve design provides additional protection against cold and wind, while the moisture-regulating properties of the material keep the body dry. The JAY-PI functional shirt is therefore the ideal choice for anyone who does not want to give up their sporting activities, even in cold weather.
