Helmet ALPINESTARS S-M3 Jettson gray / purple / black glossy. Designed for superior MX and Enduro performance, the Jettson S-M3 helmet features an advanced thermo-injected shell that optimizes impact protection while maintaining a lightweight design of just 1430g. Its patented visor release system and low-friction liner effectively reduce rotational forces, ensuring maximum safety under ECE 22.06 homologation. This helmet integrates 17 ventilation ports and hydration channels, providing exceptional thermal comfort and functionality in the most demanding conditions.

MAIN CHARACTERISTICS

• Advanced polymer shell: Manufactured using thermo-injection molding with varying thicknesses to offer an optimal balance between lightness and maximum impact protection.
• Optimized lightweight: The S-M3 model weighs 1430g (ECE) and 1460g (DOT) in size medium, reducing rider fatigue.
• High-flow ventilation: System designed with 10 intake and 7 exhaust ports to maximize heat exchange and maintain coolness in demanding conditions.
• Patented rotational protection: Incorporates a low-friction coating in the EPS liner that reduces rotational acceleration forces in oblique impacts.
• Visor release system: Patented mechanism that releases the visor with a predetermined force to mitigate loads transmitted to the neck during a fall.
• Internal and external surfaces designed to minimize the effects of oblique impacts.
• Five EPS densities distributed across five internal zones for effective volume management and impact performance.
• Hydration tube channels integrated into the cheek pads optimize functionality while riding.
• Comfort liner made from recycled materials to reduce carbon footprint.
• Customizable fit via the crown and cheek pads, available as genuine replacement parts in various thicknesses.
• Optimized chin bar with a reinforced shell structure and thickness, exceeding Alpinestars' internal homologation standards for superior impact performance.
• Internal and external surfaces designed to minimize the effects of oblique impacts.
• Emergency release system with removable 3D contoured foam cheek pads for safe helmet removal.
• Soft 25mm textile chin strap for optimal safety and comfort.
• Stainless steel D-ring closure system for a precise and secure fit.
