Alpinestars S-M5

Lightweight helmet with multiple density EPS, comfort washable liner and hydration tube channels

The S-M5 helmet is the result of more than five years of intensive study, development and testing. Scrutinizing every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort. This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness. A five density EPS liner ensures the correct density for enhanced impact absorption. Other key design features include an engineered raised area with padding to effectively reduce the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
