ALPINESTARS MENS Supertech M10 Ampress Helmet

The S-M10 shell sizing solution ensures each helmet fit size has Its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide providing 4 different helmet shell sizes S M L and XL and 6 consumer sizes from XS to XXL to ensure riders have the correct fit which not only improves comfort and reduces overall weight but most importantly improves the effectiveness of the helmet in an impact. The helmets shell construction utilizes a highly advanced molding technology with a multi-composite combination: 1) 3K carbon high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell 2) Uni-directional carbon composite layer that gives significantly greater radial strength around the shell preventing compression but allowing controlled deflection for reducing transmitted impact energy and 3) Ararnid fiber layer which provides critical penetration protection. This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the 4 density EPS liner. The result of the unique shell lay-up process employed in the S-M10 construction results in extremely effective impact protection. The S-M10 returning linear and oblique impact performance which exceeds current helmet regulation standard limits. For direct linear impacts which is an impact at a 90-degree angle between the helmet and an object the SM10 surpasses the new ECE 22.06 standard for 2024 by an average magnitude of 46% for regular-speed impacts. New for the ECE 22.06 standard new requirements now include low-speed and high-speed linear impacts where the SM10 surpasses the new ECE 22.06 Peak Linear Acceleration standards by 23% and 28% respectively. And for rotational acceleration and oblique impact performance where impact energy comes from an angle other than a linear 90-degree or right-angle straight impact the SM10 exceeds the new ECE 22.06 Peak Rotational Acceleration standard by 76%.
