Alpinestars Supertech M10 Helmet Review

The base of the M-10 has been sculpted to give a relief section, where the bottom profile is raised to clear the collarbone (Clavicle). Also, incorporated into the area of the base pad, where it sits over the riders’ collarbone, is an energy absorption pad; a more flexible compound rubber section which allows deflection when it contacts the Clavicle.
