Our new Trail Running range has been developed with more technologies, more efficient fibres and clever construction. Designed in seamless micro-fibre, our Trail Running tops will give you unique ergonomic support during the effort. Its postural 3D helps you to keep a correct and straight position. All shirts incorporate our new OnOff Ventil’action fibre. The OnOff fibre automatically increases oxygenation during intense effort by opening its thousands of alveoli. By closing its alveoli, the OnOff Ventil’action fibre protects you from cold and muscular oscillations during descents. Your comfort is guaranteed. You will do climbs and descents one after the other, with the feeling of being coached for higher performance.
