XSF's exclusive technology creates balls as a single unit, not by fusing parts together under old methods. By getting rid of seams, we also got rid of unevenness in shape, weight, and thickness that prevented a clean and accurate bounce in the past. XSF eliminated those inconsistencies in performance caused by the ball, not by you.
Seamless balls have no soft spots. XSF is tougher, more durable, and consistent all around.
