ALPINESTARS MENS SM5 CORP HELMET

An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force Irrespective of the angle of impact. - 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. - 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. - 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 - The Inner and outer surfaces are engineered 10 minimize the effects of oblique impacts. To help fight and mitigate those rotational impact forces Alpinestars has designed yet another 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 SMS scores 70% under the new regulation. - Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption
