The all-new SM5 helmet is the result of over five years of intensive research and testing from Alpinestars. It has been carefully engineered to be a lightweight helmet with a thermo-injected shell and a special polymer blend for optimal protection and comfort. The five-density EPS liner enhances impact absorption, while key design features include a raised area to reduce collarbone forces and a patented visor release system for consistent performance regardless of impact angle.
