Featuring one of the lowest aerodynamic drag measurements recorded on a cycling jersey, the Mavic Men's CXR Ultimate Jersey keeps you faster than the competition. Its streamlined CX Shell membrane offers high air impermeability, radically reducing drag when you're riding fast. And although you'd expect it to be non breathable with its high air impermeability, the membrane's pores open when the fabric is stretched for extra breathability on the move. Strategically placed Micro Vents increase breathability, while Air Mesh side panels with engineered Flash fabric provide rapid evaporation of built up perspiration. And if that's not enough tech for you, the sun reflecting Coldblack finish keeps you cooler when you're riding under the hot midday sun. Other key features include a reflective full length zipper, three rear pockets, as well as a zippered, water resistant smartphone pocket. Lightweight Ergo Grip SL sleeves provide optimal support without constricting bloodflow, courtesy of non constricting elastic.
