LS2 MX701 EXPLORER MOTORCYCLE MOTOCROSS HELMET LS2 visors are built with 3D Optically Correct "A Class" Polycarbonate, a space-age polymer with high resistance to impact, that avoids distortion and offers maximum clarity. To ensure good protection the helmet must fit your head to perfection, special attention should be paid to the shell shape design and materials to minimize the effects of a possible impact. It is key to obtain a perfect fit to your head from outside to inside, as well as the shell, the configuración of the EPS liner, which should match closely the human head shape.
