Alpinestars S-M7 Cast Helmet — Size L, Blue

The S-M7 Cast Helmet is engineered for off‑roading racing and optimized to deliver superior ventilation and comfort in a lightweight shell.

Its aerodynamic composite shell and streamlined profile reduce external load points and promote deflection for more efficient energy transfer away from the head and neck.

• PLASMA energy-dissipation system at the lower shell edge for optimized collar-bone-area protection.
• Visor detaching system designed to automatically release above 15 Joules to minimize anchoring weaknesses during impact.
• Ultra-ventilated layout with 20 ports (13 intakes and 7 exhausts) to maximize airflow.
• Communication-system compatible with a left-side EPS cutaway and earphone recesses on both sides.

Comfort features include removable, washable linings with antimicrobial treatment, interchangeable 3D cheek pads with emergency extraction system and hydration-channel routing, and an elastically connected crown and neck pad for improved oblique-impact management.

Construction balances protection and weight using a mix of fiberglass, EPS and engineered polymers to offer reliable impact performance without unnecessary mass.
