Alpinestars SM-5 Solid Helmet

Constructed from a special lightweight and impact resistant thermoinjectedpolymer results in a significantly lighter helmet with increased structural strength and outer shell uniformity in two outer shell sizes. Inner shell includes multi-density advanced EPS construction for optimal impact absorption performance in three sizes. Features two concepts for impact energy management including a resin-coated inner shell surface that noticeably improves impact resistance and reduces linear acceleration values and an elastic joint to connect the helmetGÇÖs inner shell and comfort liner to move independently in a crash scenario with an oblique impact, thereby spreading the energy forces from an impact, reducing rotational acceleration. Uses Alpinestars Emergency Release System (ERS) consisting of removable cheek pads for safe, quick, easy and safe removal of the helmet by trained medical professionals/ emergency responders in the event of a crash. The ERS features easy to locate pull-tabs for rapid release of the cheek pads, thus minimizing risk of additional injury. Includes a multi-angle, quick-release visor system that is flush over the helmetGÇÖs shell to diminish the visor protrusion from the helmet thereby enhancing safety, doesnGÇÖt use screws used in the visor for increased levels of safety and convenience to be easily adjusted and allows for ease of detachment from and reconnection to the helmet in order to facilitate helmet cleaning and maintenance. Designed to offer exceptional ventilation to prevent overheating on warm track/ trail days, with the inner air network channeling combining with the outer-shellGÇÖs multi-air inlets and exhaust ports for effective ventilation and high levels of heat transfer exchange. Hydration tube compatible channels are intelligently integrated into the helmetGÇÖs cheek pads for convenience and performance. DOT FMVSS218 and ECE 22.05 certified.
