MIPS brain protection system, reduces rotational forces to the brain. Plastic visor screws and brass inserts for easy break-away upon impact. EPS extends lower in occipital area [rear of the head] for extended protection. Anatomical "3D" contoured cheek pads with emergency release system for EMS responders. Technologically advanced composite shell construction. Three separate EPS inserts with varying low and high speed impact-specific densities. Expanded polypropylene, or EPP, chin bar liner for multi-impact performance. Removable snap-in, washable comfort liner. High flow intake system with 22 intake passages and 6 large, rear exhaust vents. Massive air flow ducts utilize negative pressure to draw hot air away from riders head and promote massive cooling, a significant advantage in warm riding conditions. Comes with TLD drawstring helmet bag. Exceeds DOT standards. MIPS MIPS (Multi-Directional Impact Protection System) is a specialized helmet safety technology that is now being used in the top tier of off road helmets in order to greatly lessen the chances of traumatic brain injury. By integrating an engineered low-friction layer into the liner of the helmet, MIPS enables a relative sliding motion between the head and the helmet so angular and rotational impact forces are absorbed and deflected. Since most head impacts occur at oblique and unpredictable angles, helmets with MIPS Technology are able to offer better protection than helmets without.
