Well, the price of that helmet i bought for 150 pounds has risen to 335 pounds now. It is a good fit and lightweight fibreglass. I was looking at what appeared to be the same helmet by HJC and it is a polycarbonate hence only 80 pounds. I really need to try one on so wait for the February Shepton show maybe.
Of course, quality never comes cheap and you only get one head. Most expensive one i bought was 15 years ago at 450 pounds for Schuberth but the lining began to fall apart. I bought another and that has become the same with lining deteriorating. Nice helmets and super light though
