[Black White Orange Fluo Matt]

[Light Grey Black Silver Matt]

The SM5 helmet is the result of more than five years of intensive studies, developments and tests. Alpinestars has taken every possible aspect under the microscope to develop a helmet that is safe and thoughtfully constructed and provides optimal protection and comfort. This lightweight helmet features a thermo-injected shell with a special polymer blend enhanced by varying material thicknesses to ensure the optimal combination of impact protection and light weight, while the five density EPS inner lining ensures the right density in the right area for improved impact absorption. Other important construction features include a raised area with padding to effectively reduce the forces transferred to the collarbone, as well as a patented helmet shield system that ensures that the helmet shield is released with the correct pre-determined force, regardless of the impact angle.
