The Alpinestars Supertech M10 Jett helmet redefines the standards for motocross safety and performance.

Its careful design offers a clean aerodynamic profile, designed to reduce air resistance while avoiding breaking points in the event of an impact.

Its innovative shell allows for efficient energy deflection during impacts, protecting the skull and limiting repercussions on the cervical vertebrae.

Add to that exceptional ventilation and featherweight, and you have a helmet built for endurance, speed and absolute comfort.

FEATURES :

• The helmet shell uses advanced molding technology, combining several composite materials: 3K carbon, unidirectional carbon composite and aramid fiber.
• The high-density 3K carbon outer layer improves hull strength and energy dissipation efficiency.
• The unidirectional carbon composite layer provides significantly greater radial strength, preventing compression while allowing controlled deflection to reduce energy transmitted upon impact.
• The aramid fiber layer provides essential protection against penetration.
• All of these layers benefit from epoxy resin bonding, guaranteeing optimal strength and advanced energy management.
• The limited deflection of the outer shell allows for better energy distribution over a wider surface area, optimizing absorption by the quadruple density EPS liner.
• The exclusive shell lamination process used for the S-M10 provides extremely effective impact protection.
• For direct linear impacts, the S-M10 exceeds the new 2024 ECE 22.06 standard by an average of 46% for normal speed impacts.
• In low and high speed linear impacts, it exceeds the standards by 23 % and 28 % respectively.
• For rotational accelerations, oblique impacts and straight right-angle impacts, the S-M10 exceeds the ECE 22.06 standard by 76 %.

PROTECTION :

• The S-M10's shell sizing system ensures that each helmet size has its own dedicated shell, for an optimal anatomical fit.
• The chin bar has been redesigned with a contoured base specifically to clear the collarbone and reduce the risk of injury.
• A softer EPS liner extends slightly beyond the helmet shell and is covered with a more flexible rubber compound to further limit the risk of collarbone injury.
• The patented A-Head system allows easy adjustment of the helmet's tilt and height on the head.
• Ultra-ventilated helmet with 28 independent ventilation openings (outside the field of vision): 18 air intakes and 10 exhaust ports.
• New Eject technology, including an emergency helmet extraction system.
• Removable semi-soft polymer side pads for increased protection and better energy distribution in the event of an impact.
• MIPS (Multi-Directional Impact Protection) system.
• ERS (Emergency Release System) for the visor, with a visor extension to protect against splashes and the sun.
• Lightweight : 1260 g (ECE standard), 1310 g with side pads and 1370 g with visor extension.
• Complies with ECE R 22.06 standard.
