ALPINESTARS Supertech M10 Helmet Ampress MIPS® Matte Black/White XL 83008231121XL

The S-M10's design offers a smooth, attractive, aerodynamic profile which is streamlined and free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet's construction. Surface curvature promotes reduced friction on impact, allowing deflection and transfer of energy to protect the rider's head from direct force to the skull and referred to the neck and spinal column. The S-M10 shell sizing solution ensures each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs, thus ensuring riders have the correct fit to improve comfort, reduce overall weight, and improve effectiveness of the helmet in an impact. Chin bar's base area specifically sculpted to give a relief section and raised to clear the collarbone. Soft EPS liner extends beyond the helmet shell itself and is covered by a flexible rubber compound providing a reduced chance of any sort of collarbone injury. A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head. Ultra-ventilated helmet with 28 individual intake and exhaust ports, not including the eye port, with 18 intakes and 10 exhausts. Eject technology includes the eject helmet removal system. Rotational acceleration and oblique impact performance. Removable side pads, made from a semi-soft polymer for added protection, provide contact area to help spread impact energy. Emergency Release System (ERS) Emergency Visor Release and Visor Extension provides protection
