Alpinestars S-M5 Sail 2024 Motocross Helmet
Brand New SM5 ECE 22 Helmet. 06 was developed to provide MX riders with a helmet which is safe and specially designed to provide optimal protection and comfort. The lightweight SM5 helmet features a thermal injection shell including a special polymer mixture, increased by varying thicknesses which is designed to provide the optimal combination of impact protection and lightweight. The inner liner is a seven-piece expanded polystyrene (EPS) construction , including five different EPS densities designed to provide the correct density in the desired area to improve shock absorption.
Features:
Lightweight outer shell made from technologically advanced impact resistant material. thermoplastic in three anatomical shell sizes plus three separate sizes of EPS foam inner liner with a combination of inner liner and cheek pad which provides 6 unique sizes and provides the best fit and protection. Specially designed raised padded area effectively reduces forces transmitted to the skin. collarbone and patented visor release system which ensures the release of the helmet visor with the correct preset force , regardless of the angle of impact. Changed the volume of the lower part of the middle case large, XL and 2XL, it is now about 3%. wider to make it easier to put on and take off the helmet At the same time, increasing the volume of the helmet also improved impact management characteristics which are now 44% below the normal speed threshold.
In accordance with the new ECE 22 standard. 06 SM5 achieves 44% higher normal speed impact resistance compared to the current 33% and 32% higher linear impact at low speed and 31% higher at high speed than the prevailing standard. The inner and outer surfaces are designed in this way to minimize the effects of oblique impacts. To help combat and mitigate these rotational impact forces Alpinestars has developed patented technology creating a low friction surface on the inner surface of the polystyrene foam liner. According to ECE 22 standard. 06, which now includes an oblique spin kick rating SM5 scores 70% under the new rules.
Multi-density liner provides the right density in the right area for improved shock absorption.
Changed new chin profile where the bottom has been specially shaped to create a raised section elevated to release the collarbone with new softer polystyrene foam lining which extends beyond the helmet shell and is covered with a more flexible rubber compound which reduces the likelihood of any damage. collarbone injury
Maximum ventilation and high heat exchange thanks to multiple air intakes and outlets
The helmet visor is designed in this way to direct air into the holes for improved airflow.
ERS emergency release system cheek pads
Hydration hose loops for easy hydration system installation.
