I'm in the market to finally buy my own helmet for use in autox and karting, with the option to use it on the track for driving schools (not competitive). I'm not sure I need an SA, I think an M2005 is good enough (but correct me if I'm wrong).

My situation is that all the loaners I've used have demonstrated that I need a helmet that accomodates wearing glasses too. Contacts are not an option for me because they bother my eyes.

Is there a particular helmet type/brand/model (prefer full face) that better accomodates wearing glasses and what do other people do?
