HJC… cheap, decent helmets… cl-## can be bought brand new for under 150 bucks
Z1R makes helmets for cheap too… some of them are under 100
Shoei and Arai cost alot more, and for a car purpose, i hardly expect quality venting to be that big an issue…
SIMPSON and Bel are the name that comes to mind when i picture car helmets
Freewheeling cycle has always been good to me when buying stuff… just go in and talk to the right people
