Wasnt chest protectors made back in the day to protect your chest from back tire roost on the track? What do YOU think? Is it needed for trailriders ? Needed for trail riding, imagine sliding down a trail of shale rock, the chest protector will save your innards, otherwise, the shale would split you wide open dumping all your guts on the trail! OK, so I'm a little extreme, but I wont ride without it. I'll putt around without it is all.
