Great fitting helmet and light weight would highly recommend. Went to this from another well known brand and didn’t realise just how bad other helmet was until wearing this 1!

Excellent helmet as usual with HJC. I have been wearing HJC for many years now and never been disappointed with the fit and quality. Everything seems to be improved when a new model comes out with the air flow through the helmet keeping your head cool when needed and the aperture giving great views. Basically I think they are brilliant. Sportsbikeshop are absolutely amazing to deal with as well.
