Take the design of the FS-15 from HJC and add carbon fiber. Instead of a standard fiberglass shell the construction is made up of a lightweight carbon fiber. By taking off a few ounces on the helmet, it reduces neck fatigue, resulting in better rider performance and comfort. All the crash protection is no good if you cannot see. The optically correct shield is distortion free and can be removed and installed without tools which make a quick change at any time. Match up the performance of the lightweight carbon FS-15 helmet with that great looking carbon on your bike.
