The coveted 2019 Tour of California Leader Jersey, worn by the rider with the lowest overall race time.. The official ASSOS “yellow jersey” of the 2019 Tour of California goes to the rider with the lowest cumulative race time. Featuring race sponsors, a contrasting sleeve, and the iconic grizzly bear of The Golden State, this is what the GC contenders will have in their crosshairs throughout the race.. The body-mapped paneling follows our proven regularFit pattern, complemented by its light, fast-drying double yarn textile that excels in moving moisture away from the skin. From there, we borrowed a few design cues from our favorite long-distance jerseys, including an open mesh at the underarms for increased airflow, our proprietary reinforced pocket system that stabilizes the cargo load, fold-over stitching at the cuffs and front hem, a slim full-length zipper, and a light silicone grip along the rear hem for a locked-in hold, regardless of upper body position.
