Built for the hard charger, the Super DH is most at home on steep terrainfeaturing Spherical Technology and full DH certification. Spherical Technologys Ball-and-Socket design, powered by MIPS, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. The Super DH is loaded with additional featuresincluding a 360-degree wraparound, tool-free removable chin bar beefy enough to satisfy the rigors of ASTM 1952 testing, a huge eyeglass and goggle-friendly eye port, an adjustable-height visor, snap-in camera mount, Overbrow Ventilation and X-Static padding, and a quality fit that is second to none. The end result is uncompromising protection and performance, and unparalleled versatility. The Super DH is ready to take World Cup DH runs on the chin, bang out bike park laps until the chairlifts stop running, or settle into hours of back-country uphill grinding in search of that perfect ribbon of high-consequence singletrack. - FUSION IN-MoIding POLYCARBONATE SHELL AND PROGRESSIVE LAYERING - A process pioneered by Bell bonds the helmets outer shell to the EPS foam liner to create a sturdier helmet. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts. - FLEX SPHERICAL+MIPS AND WRAPAROUND CHIN BAR - Flex Spherical enhances our ability to address high-speed impacts, low-speed impacts, as well as rotational impacts. Think of it as comprehensive protection, with the added bonus of being able to design better helmet ventilation. A removable protective chin bar, designed for trail riding adaptability. No tools required. Warning: all chin bars have limits, and serious injury or death can occur. Read the owners manual carefully before using your helmet - X-STATIC AND XT2 PADDING, SWEAT GUIDE AND FLOAT FIT DH W/ FIDLOCK BUCKLE - Quick-drying materials, woven with real silver fibers.
