Alpinestars S-M7 Cast Helmet — XL, Blue

🏁 Engineered for off-roading racing, this helmet is optimized to deliver superior ventilation and comfort in a lightweight, aerodynamic composite shell.

The streamlined shell geometry promotes deflection on impact and efficient energy transfer to help protect the rider's head and reduce load to the neck and spine.

Key features

• A-head fitment and visor detaching system with integrated PLASMA energy-dissipation at the lower shell edge for improved collarbone-area protection.
• Ultra-ventilated design with 20 intake and exhaust ports (13 intakes, 7 exhausts) for continuous airflow.
• Aerodynamic profile free of external channels or load points to preserve structural integrity on impact.
• Cheek pads with 3D foam and emergency extraction system, interchangeable across shell sizes; integrated channels for hydration tube installation.
• Removable, washable linings with antimicrobial fabric treatments for easy maintenance.

Construction

The composite shell combines multi-density materials and EPS liners to balance lightweight performance with impact protection. Crown and neck pads are elastically connected to manage oblique impacts, and the top pad is removable and height-adjustable via the A-head system.

Protection

The visor detaching system is engineered to release automatically under impact energies above specified thresholds to avoid creating anchoring weak points.

Integrated PLASMA technology is positioned at critical side-pad locations to enhance shock absorption and reduce the risk of localized injury. 💨
