Yeah it is fire proof material. Been doing more reading. I also read that the SA is tested smashing up against a roll bar. The M would need to be stronger I would think..... Reason is your not strapped into anything.... Lol, Have you seen them Motorcycle guys crash and bounce their heads off the pavement! Damn.......
Yeah I crashed head first , foam inside helmet compressed about 1.2 inch or more . Head was the size of a basketball , lots o swelling . Without a helmet , well think watermelon dropped from 30 feet .
