Alpinestars Supertech M10 Acumen Le Helmet Red Flake/Black/Silver / Medium

Shell construction utilizes a highly advanced molding technology with a multi-composite combination: 3K Carbon high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell. Uni-directional carbon composite layer gives significantly greater radial strength around the shell preventing compression but allowing controlled deflection for reducing transmitted impact energy. Aramid fiber layer which provides critical penetration protection.
