The evolution of an icon. The UYN underwear tested and recommended by the top national teams in the world becomes even more powerful. In the new version of the UYN NATYON shirt we have reduced the weight by 34% compared to the previous model thanks to a new design and the use of the bio-based yarn Natex. At the same time, we were able to increase the elasticity by 4% for even greater freedom of movement. The breathable surface area of the Gradual Coolvent technology has increased by 58%, at the chest, back and underarm. This keeps the body dry and at a stable temperature even during the most stressful races. Tests in the lab and on the ski slopes led us to introduce new features, such as Meta-Ribs at the shoulders that stabilise and support the shoulder muscles and Pressure Branches at the elbows that protect and relieve pressure on the joints. Targeted compression, more intense at the extremities, promotes blood circulation to reduce fatigue.
