Alpinestars Supertech SM5 MINE GRAY Cross Motorcycle Helmet

Made from a special, lightweight, impact-resistant thermo-injected polymer, this helmet is significantly lighter and features increased structural strength and uniformity of outer material in two sizes.

The inner shell features an advanced multi-density EPS structure for optimum impact absorption, and is available in three sizes.

Feature two impact energy management concepts, including a resin-coated inner shell surface that significantly improves impact resistance and reduces linear acceleration values, and an elastic joint that connects.

the helmet's inner shell and comfort liner to move independently in an oblique impact crash scenario, thereby distributing impact energy forces and reducing rotational acceleration

Use the Alpinestars Emergency Release System (ERS) of removable cheek foams for safe, quick and easy helmet removal by trained medical professionals/emergency responders in the event of an accident.

The ERS features easy-to-locate tabs to quickly release the cheek foams, minimizing the risk of further injury.

Equipped with a multiple-angle, quick-release visor that is flush with the shell to reduce the protrusion of the visor from the helmet, thereby
to improve safety.

No screws are used in the visor, for easy adjustment, added safety and convenience, and easy removal and repositioning during helmet cleaning and maintenance operations.

Designed for exceptional ventilation to prevent overheating on hot days on the trail. The inner ventilation channel combines with the multiple air inlets and outlets of the outer shell for efficient ventilation and high levels of heat exchange.

Hydration tube-compatible channels are cleverly integrated into the helmet's cheek foams for added convenience and performance.
