With all this time sitting down at the moment (knee op 3 weeks ago) my thoughts have been drawing towards doing a track day when I can finally drive again. (Hopefully around the start of November) I want to buy a Helmet that is SNELL specification so that I can do future trackdays without concern. I have seen Hedtec ones advertised does anyone have any experience of them or any recommendations for other ones less than say £200 or am I being unrealistic?
