Alpinestars S M5 Mineral 2024 Motocross Helmet, light gray, L (59/60)

Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury ERS Emergency Release System cheek pads For the new ECE 22.06 standard, the SM5 achieves a 44% better regular-speed impact rating compared to the current 33% figure, as well as a 32% better low-speed, and 31% better high-speed linear impact score than the prevailing standard Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three anatomical shell sizes, plus three individual EPS inner liner sizes with a combination of inner lining and cheek padding to offer 6 unique sizes and to ensure the best fitment and protection a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight. The inner liner a 7-piece expanded polystyrene (EPS) construction including five different densities of EPS designed to ensure the correct density in the correct area for enhanced impact absorption. Features #Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three anatomical shell sizes, plus three individual EPS inner liner sizes with a combination of inner lining and cheek padding to offer 6 unique sizes and to ensure the best fitment and prot Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented helmet peak release system that ensures the helmet peak is released with the correct pre-determined amount of force, irrespective of the angle of impact Revised the medium, large, XL, and 2XL lower shell volume to be around 3% wider to make the helmet easier to put on and take off, where the increase in helmet volume has also improved the impact management performance which is now 44% lower than the regular-speed threshold The inner and outer surfaces are engineered to minimize the effects of oblique impacts. To help fight and mitigate those rotational impact forces, Alpinestars has designed a proprietary technology by creating a low friction surface on the inner surface of the EPS liner. For the ECE 22.06 standard, which now includes the rotational oblique impact rating, the SM5 scores 70% under the new regulation Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption
