Cool goes both ways on our #1 Racing Performance Short Sleeve Shirt. That’s because this men’s button-down has a mesh upper back panel to welcome airflow plus cool embroidered graphics that pay tribute to our proud racing heritage. Its relaxed fit is cut from lightweight cotton/polyester twill that’s washed for softness. Features reflective piping for added visibility, and a hidden snap-down collar that won’t flap around under riding gear. Know the history—the #1 Logo featured on back debuted in 1969 to honor our AMA Grand National Championship Title.
