Alpinestars S-M5 Scout Helmet Black / Silver. The new SM-5 is the result of more than 5 years of intensive study, development and testing. All aspects have been studied to make a very safe and comfortable helmet. Made of thermo-injected polymer with varying degrees of thickness, it is characterized by being very light and ventilated. The visor has been designed to detach in the event of a possible fall. Technical features: Very light outer shell made of resistant advanced thermoplastic material. 2 sizes of outer shell to perfectly adapt to the physical complexion of each rider. The exterior and interior surfaces have been designed to minimize the effects of oblique impacts. Inner shell of 5 different densities in certain areas to offer a great capacity to absorb impacts. The Supertech S-M5's visor has been designed to detach in the event of a fall. It comes off in a given degree of force and at any angle. Provides maximum ventilation thanks to multiple air inlets and air extractors on the back to extract hot air from inside the helmet. The visor has been aerodynamically designed to direct the air directly to the air inlets to offer perfect ventilation. The lower part of the helmet has been made of soft EPS foam and has been designed to minimize the risk of the energy generated by an eventual impact being transmitted to the clavicle area.
