The Flexair Jersey is designed to function seamlessly with the human body. It's cut from lightweight and flexible materials which anticipate your every move. The championship-winning jersey has been refined to maximize breathability and increase mobility. But some things never change—TruDri® fabric continues to be the foundation of the jersey, rapidly wicking moisture to keep you cool and dry. Active-fit sleeves with articulated darting provide a contoured fit while in a dirt bike riding position. Laser perforated venting throughout the arms increases breathability.
