Never too expensive when it comes to safety paid well over 500 quid for my first one nearly 20 years ago.
Don't know why I'm looking at this because I'm never happy with a new helmet even though I have had to learn and relearn the lesson on too many occasions to try before you buy. Its not like you can try them for a week of so. Reviews never seem to help and I cling on to the same old helmets for far too long (dare not say how long). Might be an age thing because I cant remember it being a consideration when I was younger, if it fastened and didn't fly off when you were going faster than you ought to I was happy. I really need (not want) a new helmet, just going to have to grit my teeth and get on with it.
Afraid I’m gonna have to stop you there… lol
Do they do XXXL as I have the biggest melon head you have ever seen
I have the original GT Air, and basically most helmets were tight on my forehead specially Arai. It would possibly be a good fit for you. Its not a great time to go shopping and being indoors but the best thing to do is to go to a shop and try it on for 15 - 20 mins while walking around. My head is a round shape and the gt air was the only one I could use. Its a very personal thing so I wouldn't go on online advice, you have to try it on. It has to fit you right for it to be safe.
