The Fly Racing Kinetic K121 MX jersey is designed specifically for off-road riding. It features a standard fit—not too tight or loose for optimum comfort. The tagless comfort-stretch collar with gusset offers exceptional comfort, and the short elastic sleeve cuffs are relaxed. The multi-panel construction with mesh ventilation in critical areas provides outstanding comfort and air circulation at your sides and underarms for optimum comfort. The extended tail keeps your jersey tucked in.
