The SM5 helmet was designed to provide MX riders with a safe helmet specially designed to offer protection and comfort optimal. The lightweight SM5 helmet features a thermo-injected shell that incorporates a special blend of polymers enhanced by different degrees of thickness, designed to offer an optimal combination of impact protection and lightness, while the internal membrane Five-density EPS ensures the right density in the right area for greater impact absorption.Data sheet: An engineered raised area with padding effectively reduces forces transmitted to the collarbone and a patented visor release system ensures that the visor is released with the right amount of pre-determined force, regardless of the angle of impact. The lightweight outer shell is made of technologically advanced impact resistant thermoplastic in three anatomical shell sizes, plus three EPS inner liner sizes with a combination of inner liner and cheek padding to offer 6 unique sizes and ensure the best fit and
