Agreed, I forgot about the sharp metal we ride around....there you have it, the real benefit of chest protectors. Maybe they should be called upper body protectors.
I have broke ribs with one on too. I think Jason was talking about a puncture wound. Now I can say that hasn't happened yet, although I have had some serious road rash while wearing one, because they can move on you. Come to think of it, I wore one during the infamous bike vs quad wreck with Jason, my back was jacked for a week, and that was a tip over.
