I wear the Hein Gerrick leathers for street/sport riding, They have what they
call body armor in them. It is not hard plastic, however, it is compressed
foam. I am sure it adds additional padding to cushion an impact, but I am
also sure it is not going to be a miracoulous reduction in the event of an
impact. It took a little getting used to riding with it, because you can tell
it is there and it is a little restrictive. I don the leather pants and
leather jacket when I intend to hit the twisties. On short commutes, I only
wear the leather jacket. I feel safer with the stuff than without it,
figuring every little bit of added protection helps. Pat and I have talked
about getting the strap on back protector, as an added measure of safety.
