The SCHUBERTH C4 PRO is the new benchmark for the most demanding tourers and racers. It combines cutting edge technologies with top-grade quality: the helmet has a compact shape that barely resembles a flip-up helmet. The new interior, the optimized acoustic design, and the high- performance technology make the SCHUBERTH C4 PRO the most comfortable flip-up helmet. Low noise level no matter what the speed. Already compatible with the new, invisible SC2 and SC1 communication systems.
