The all-new SM5 helmet is the result of more than five years of intensive study, development and testing. This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five density EPS liner ensures the correct density in the correct area 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.
