The designed of the S-M10 helmet is consistent with the Alpinestars philosophy and shares distinctive themes with other products of th brand: a smooth and eye-catching profile, tapered and free of external elements and channels that could act as a loading point in case of impact or compromise the overall integrity of the structure. The surface curvature promotes the reduction of friction at the time of impact, allowing more efficient deflection and energy transfer to protect the pilot's head from direct force on the skull and from force transmitted to the neck and spine. The helmet is designed to accomodate a wide range of goggles, and the air intakes on the shell are positioned so as to maximize ventilation efficiency.

CHARACTERISTICS:

The shell of the S-M10 has been designed with performance as a priority and design that uniquely identifies the brand. Another key feature is the sizing solution of the S-10 shell; each helemt size has its own specific solution of the most anatomical solution for the wide variety of fit needs worldwide. 

MATERIALS:

The construction of the helmet shell uses highly advanced molding technology with a multi-composite combination:

• Carbon 3K, high density carbon outer layer that improves the strenght and efficiency of energy dissipation on the shell. 
• Unidirectional carbon composite layer that offers significantly greater radial resistance around the shell, preventing compression but allowing controlled deflection to reduce the transmitted impact energy. 
• Armid fibre layer providing decisive protection against penetration
• This combination of layers offers even higher performance thanks to the epoxy resin that offers the best energy distribution; the limited deflection of the outer shell causes the energy to spread widely and is better absorbed by the EPS lining. 

The result of the unique shell layering process used in the construction of the S-M10 is extremely effective impact protection.
