Hmmm..not sure if this is what you're looking for. But how about a more flexible vest which offers the same if not greater type of protection. There are certain areas that are exposed on at least my vest which would be nice to be covered up somehow. Just a thought, not sure if this is what you were looking for.
Be advised, I'm mean nasty and tired. I eat concertina wire and piss napalm and I could put a round through a fleas *** at 300 yards. So why don't you hump somebody else's leg mutt-face before I push yours in.
