I bought this shirt for my son because he pitches in Little League. After reading a story about a boy get hit in the heart with a line drive I was terrified to let him pitch, but that was a freak accident and my son loves to play baseball so I wasn't about to not let him pitch. However freak accidents do happen so I bought this shirt to give me a little peace of mind. It is comfortable for him to wear and runs true to size. He likes that it makes his chest look bigger! The thing with a product like this is I won't know how well it works unless it he gets hit there so I hope I never have to find out, but for $35 if it ever does happen this shirt may save his life. Small price to pay for added security in my opinion.
