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, and has been race-proven in some of the most demanding conditions by some of the world's top motocross athletes. The championship-winning jersey has been refined to maximise 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. TruDri main body fabric provides a soft, lightweight fit with true moisture management. Dyed main body fabric with premium heat transfer logo treatments. Bonded collar to reduce chaffing. Bonded stretch cuff provides a slim athletic fit. Lightweight construction for complete freedom of movement.
