Supertech M8 Radium 2 HelmetShell construction utilizes a highly advanced molding technology with a multi-composite combination. 3K Carbon, high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell.Uni-directional carbon composite layer that gives significantly greater radial strength around the shell.The result of the unique shell lay-up process employed in the S-M8 construction results in extremely effective impact protection. With a fully equipped helmet testing facility, within Alpinestars Racing Development Center, an exhaustive impact research program has resulted in the Supertech M8 returning linear and oblique impact performance which far improves upon current helmet regulation standard limits. For direct, linear, impact by an average magnitude of 41% and for rotational acceleration, oblique, impact performance by an average of 48%.Aramid fiber layer which provides critical penetration protection.Combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management.Shell has been profiled with performance as a priority and with a design style that identifies the profile of the helmet and its sculpted surface as uniquely ‘Alpinestars’. Each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide.
