Endurance engineered. Alleviating much of the discomfort inherent to riding long distances, the Mavic Men's Ksyrium Pro Long-Sleeve Jersey emphasizes lightweight warmth and a bit roomier cut. Ergonomic seams closely follow the body's contours, reducing irritation while promoting freedom and flexibility. Ride Wick ST fabric pulls perspiration away from your body where it can readily evaporate. Ultimately, this prevents the soggy, sweat-soaked feel as you ride. Air Mesh side panels channel cool air across your body as you zip down idyllic country roads. Smooth flatlock seams won't scratch sensitive skin, which is especially important when you're in the saddle for hours on end.Mavic's signature Ergo Grip cuffs retain a secure fit, but without pinching or uncomfortably digging into your skin. The full-length zipper employs a stay-put zipper pull, providing extra ventilation and cooling when you're on the verge of overheating. As a handy bonus, three rear pockets store riding accessories separately from the zippered rear pouch. This allows you to partition sticky energy gels and other messy items away from your daily essentials. Also, the rear pocket panel features uni-directional mesh to prevent stuffed pockets from sagging.
