Alpinestars Sm3 Youth Wurx Off-road Helmet For Youth Medium, Impact

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.
