Alpinestars S-M7 Cast Helmet — Size S, Blue

The S-M7 Cast blends race-oriented off-road performance with a lightweight, aerodynamic shell designed for superior ventilation and rider comfort.

Key features

• A streamlined aerodynamic profile that minimizes external load points and encourages efficient energy deflection on impact.
• PLASMA technology at the lower shell edge for optimized energy dissipation near the collar bone area.
• Ultra-ventilated design with 20 intake and exhaust ports (13 intakes, 7 exhausts) for continuous airflow.
• A-head fitment and visor detaching system with automatic release above 15 joules to protect against impact forces.
• Removable, washable linings and exchangeable cheek pads with emergency extraction system and hydration-channel integration.
• Cutaway EPS on the left side and earphone recesses to accommodate communication systems.

Construction details include interconnected crown and neck pads for oblique impact management, an adjustable top pad, and a 25 mm nylon chin strap with stainless DD rings and removable covers for washing.

Protection is enhanced by a visor release mechanism conceived to avoid common anchoring weaknesses and strategically integrated side padding for high-performance shock absorption ✅
