Technology injected foam layer directly into the hard outer shell. PC / polycarbonate is the material used in the production of the helmet shell. The polycarbonate shell is firmly attached to the EPS inner material. The EPS material is directly injected into the polycarbonate top layer to form an integral unit. The monolithic unit absorbs point impacts on a sharp object and the applied force on the helmet spreads over its entire surface, so the head is perfectly protected.
