Remember.....THE BEST HELMET IS THE ONE THAT FITS!
Try loads on and see which ones fit your head size and shape.
I use a Roof RO10. Had it now for 2 years, fit is still perfect, finish lasts well, it's quiet and doesn't mist up.
You pays your money and takes your choice, mate! Shop around and try lots of different manufacturers; not all makes will suit you. As an example, Ive yet to find an AGV that will stay on my noggin when pulled in the right way, with the strap done up tight!
There are some simple things to try with the lid on to see if it's right for you. If you want more advice on this, drop me a PM.
