I have a snell full face helmet I was required to have for Porsche track days. I'm not sure if that is still good for road use on a motorcycle. Its about 10 years old I think. I do however, have a couple of DOT approved Nolan helmets I purchased for the recent MSF course. One is an open face, kinda retro Half Helmet, and the other is modular, with a full face shield. Once I get used to the NineT enough to really take it on the road, I probably should get a new full face like a Shoei or Arai.
