Alpinestars Supertech S-M10 Deegan Monster

Alpinestars Supertech M10 Deegan Monster Motocross Helmet

The goal of the Alpinestars Supertech helmet family was to develop the most advanced, protective, and high-performance helmets for riders worldwide. With the S-M10, the Alpinestars helmet development team has created a helmet that offers a perfect blend of excellent ventilation and unmatched comfort, constructing a helmet with the lowest possible weight without compromise. The design of the S-M10 offers a smooth, attractive, aerodynamic profile that is ideally free of external channels and features that could act as stress points in an impact or compromise the overall integrity of the helmet construction. The curvature of the surface reduces friction during an impact, allowing for deflection and the most efficient transfer of energy to protect the rider's head from direct force impact on the skull, neck, and spine.

Features:

• The S-M10 shell sizing solution ensures that every helmet size has its own properly fitted shell size, providing the most anatomical solution for the widest range of fit requirements worldwide. Four different helmet shell sizes (S, M, L, and XL) and six consumer sizes (XS to XXL) ensure that the rider has the right fit, which not only improves comfort and reduces overall weight, but above all increases the helmet's effectiveness in an impact
• The patented A-head adjustment system allows for easy adjustment of the angle and height at which the helmet sits on the head
• Ultra-ventilated helmet with 28 individual intake and exhaust ports, excluding the eye opening, with 18 intakes and 10 exhausts, for optimal ventilation
• The new profile of the revised chin bar was specially shaped to create a relief that extends beyond the collarbone, with a new, softer EPS layer that extends beyond the helmet shell and is covered by a more flexible rubber compound, reducing the risk of collarbone injuries

Specifications:

• Double D-ring closure
• The result of the unique shell layering process used in the construction of the S-M10 is extremely effective impact protection. The S-M10 offers linear and oblique impact protection that exceeds current helmet standards. In a direct linear impact, the S-M10 exceeds the new ECE 22.06 standard for 2024 by an average of 46% in normal-speed impacts. In the new requirements for linear impact speeds at low and high speeds, the S-M10 exceeds the standards by 23% and 28%, respectively. In rotational acceleration and oblique impact, the S-M10 exceeds the new ECE 22.06 standard for peak rotational acceleration by 76%.
• MIPS (Multi-Directional Impact Protection System)
• Removable cheek pads made of a semi-soft polymer offer additional protection and a larger contact area to distribute impact energy
• ERS (Emergency Response System) and a new visor extension offer protection from sunlight
• The new ejection technology includes the Eject helmet removal system
• 1260g for size Medium, 1310g with cheek pads, and 1370g with visor extension

Helmet shell construction:

• 3K Carbon: An outer layer of high-density carbon that improves the strength and efficiency of energy dissipation through the shell
• Unidirectional carbon composite layer: Provides significantly higher radial strength around the shell and prevents compression while allowing controlled flexing to reduce transmitted impact energy
• Aramid fiber layer: Provides critical protection against penetration
• This combination of layers is made even more effective by an epoxy resin bond, which provides the best possible strength and energy management
