Dad works as a carbon fiber part manufacturer. My dad actually is a carbon fiber part manufacturer, so I know that there can be quite a bit of faulty carbon fiber pieces left over from an order, simply because it has an air bubble or something. It's not [i]actual[/i] armor, more just decoration. If someone punched him, it wouldn't do much, but it'd just splinter if hit by a bullet or something. It's just carbon fiber plates interlocked and strapped on, really. Most of them have little air bubbles or some other imperfection that makes it faulty.
