if you want to be a pussy and ski groomed shit runs all day, forget the helmet.  You have to be a dumbass not to wear a helmet if you are hucking cliffs, or riding the park.  If you are too cool to wear a helmet, you a jackass.  maybe if you hit your head, it might knock a little sense into you.  Helmets these days are as comfortable as a toque. I mean every other sport uses helmets (mountain biking, motocross, wakeboarding).  if you are truly hardcore, then you need a helmet, but if you just want to dick around on little shit jumps and cordaroy, use a touque.
