Alpinestars Sm3 Youth Off-road Helmet Black Matte For Mx & Enduro 2024

The SM3 Youth weighs 1060g (ECE) and 1170g (DOT). The inner and outer surfaces are engineered to minimize the effects of oblique impacts. This layer essentially acts as a slip plane to mimic the brain’s own low friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts.
