Born from racing, the all-new X-12 combines Shoei's 50 years of helmet building experience with the very latest technology and most advanced materials to bring you the racing helmet of the future. Quick Release Self-Adjusting Base Plate System: Patented new spring-loaded technology eliminates the need to adjust base plates for proper sealing. CW-1 Shield: Wider and taller than the CX-IV that it replaces. AIM+ Shell Construction: Combines fiberglass with organic fibers so strong they can only be cut with a laser. The end result is a stronger, lighter shell that will absorb and distribute the force of an impact safely and efficiently. 5 Shell Sizes: Industry-leading five shell sizes to ensure a custom fit for heads between the sizes of XS-XXL. Aero Edge 2 Spoiler: Minimizes lift and wind drag at high speeds from the rider and motorcycle. In addition, increased negative air pressure improves exhaust performance to help ventilate the helmet. Ventilation System: Five (5) intake and ten (10) exhaust vents, the most aggressively ventilated helmet ever produced. New Side Extractor Vents developed by Shoei's MotoGP racing service to help clear warm, humid air from the racer's face. Dual-Layer EPS Liner: Enhanced impact absorption by adjusting thickness and density in key areas. Inner liner features air channels for efficient cooling. Impact-absorbing EPS liner throughout the entire chin bar. 3D Max Dry Interior System: Fully removable, washable, and replaceable 3D Max Dry liner proven to absorb and dissipate sweat two-times faster than traditional nylon interiors. E.Q.R.S. (Emergency Quick Release System): Mechanical tabs disengage cheek pads for easy removal by emergency medical personnel. Helmet can be removed with minimum load to rider in emergency situations. Chin Curtain: Reduces wind turbulence and noise. Standards: Snell M2010 and DOT Warranty: 5-Year
