A light, safe and attractive helmet, worn by top class riders including young talent Bertram Allen. However is the helmet worth 700$? 

Yes, it is exactly that what Samshield says about it. Not only does the carbon fiber outside make the helmet tough but also very light to guarantee comfort while riding.

​

Another major + to the helmet is the fact that you will not start to sweat nor get warm under the helmet in summer due to its great air flow system.
