This is the best accessory for urbanites and lovers of freedom on the road. Certified ECE 22.05. GR 1000 ± 50. The visors of the Ls2 helmets are composed of Class A polycarbonate lenses optically corrected for a 3D vision and a space age polymer with a high impact resistance that prevents deformation and offers maximum clarity . To ensure good protection, the helmet must fit perfectly to the head. Special attention should be paid to the shape, design and materials of the shell to minimize the effects of a possible impact. It is essential to obtain a perfect fit to the head from the outside inwards. As with the shell, the EPS configuration with padding should fit perfectly with the shape of the head.
