I'm not a racer and never will be(too fat and old), but into tight, technical drops and just fun stupid stuff. I've got 4 main riders in my crew and all 3 of them are out right now with busted collar bones. Any of the chest protectors or "jackets" out there do the trick? I definately want one anyway, if not only for basic protection, but it would be nice to find something to protect them collar bones!
