Ever wonder exactly what an X-Out golf ball is? Why are they sold so cheap?
X-Outs are name-brand golf balls on which that brand has been stamped out, usually with a row of X’s, because of imperfections in the ball. Those imperfections are often cosmetic in nature, and usually so small as not to be noticeable. The balls usually play the same as their counterparts, or at least close enough that most recreational players could never tell the difference.
