XBionic Regulator Bike Race Zip Short Sleeve Jersey

This innovative generation 4.0 X-BIONIC® model has a super lightweight construction and benefits from the Retina® ultra-high definition manufacturing technology advantage. The award-winning 3D Bionic Sphere® system compensates for temperature with precisely positioned functional zones. It warms you up when it's cold and refreshes you when you sweat. Sweat Traps® collect sweat and transport them to intensive evaporation. The Kidney Ribs' reinforced material isolates the kidneys and pelvis from temperature sensitivity. The streamlined design of the Dolphin Rider neck is optimized for the area where the neck and helmet meet. The Flexor Arm Cuff's asymmetrical cut prevents sleeve friction and slipping.
