Socal, dont get me wrong here, all i am saying is that a chest protector is designed to stop roost, it is not designed to save your body in an accident, yes there are tons of cases where they have actually saved lives, but that was not thier design intention. Where as a full body armor and/or neckbrace is designed to save you from impact, not to stop roost. wearing a chest protector is always a good idea, but if keeping his son extra safe is his goal he should probably purchase some body armour not just hope the chest protector does the trick.
