The 5.5 UltraWeld jersey is simply unbeatable in quality and fit! It is ultra-light, has welded seems, and offers ample ventilation thanks to its air channels and laser- cut vents. The stretch mesh ensures a race fit that enables you to ride with or without body armor and a rear silicone grip keeps the jersey tucked in the pants, a welded seam at the cuff and hem make it ultra- comfortable. This jersey is the choice of champions! If you are looking for something with a more classic fit, or something for colder climates, take a look at the 4.5 gear range.
