Alpinestars S-M5 MINERAL 22.06 Gray Green Glossy Motorcycle Cross Enduro Helmet

The SM5 helmet was designed to provide MX riders with a safe and specially designed helmet to offer optimal protection and comfort. The lightweight SM5 helmet features a thermo-injected shell that incorporates a special polymer blend enhanced by varying degrees of thickness that is designed to offer the optimal combination of impact protection and lightness, while the five-density EPS liner ensures the correct density in Correct area for better impact absorption.

Data sheet:

• An engineered raised area with padding effectively reduces forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct amount of pre-determined force, regardless of impact angle.
• The lightweight outer shell is made 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 better fit and protection.
• Revised the medium, large, XL and 2XL lower shell volume to be approximately 3% wider to make the helmet easier to put on and take off, where the increased volume of the helmet also improved helmet handling performance impacts that are now 44% lower than the normal speed threshold.
• For the new ECE 22.06 standard, the SM5 achieves a normal speed impact score 44% better than the current figure of 33%, as well as a linear impact score 32% better at low speed and 31% better at high speed compared to the prevailing standard.
• The internal and external surfaces are designed to minimize the effects of oblique impacts.To help combat and mitigate those rotational impact forces, Alpinestars engineered another proprietary technology creating a low-friction surface on the inner surface of the EPS liner. For the ECE 22.06 standard, which now includes oblique rotational impact assessment, the SM5 scores 70% under the new regulation.
• Multiple density inner lining to ensure the correct density in the correct area for better impact absorption.
• New redesigned chin bar profile, where the base area has been specially sculpted to give a raised section, raised to free up the collarbone, with a new softer EPS liner that extends beyond the helmet shell itself and is covered by a more flexible rubber compound that offers a reduced chance of any type of collarbone injury.
• The patented visor release system ensures that the visor is released with the correct pre-determined amount of force, regardless of the impact angle.
• Maximized ventilation and high levels of heat exchange thanks to the air intakes and multiple exhaust.
• The ECE version of the SM5 helmet weighs 1,350 grams for a medium size, and 1420 grams for the ECE version with visor.
• The visor was designed to direct air into the ports for better airflow.
