IMO, for autox, you don't really need a full face one like this. It may get hot and it's hard to talk to someone if there is an instructor riding with you. You'll only be wearing it for about 5 minutes each time. For that price, you can get a SA rated helmet which is better in protection than the M rated. If you might take your car to a track, such as waterford hills or gingerman, they don't allow M rated helmets.
