Alpinestars S-M7 Helmet — Size S, Black

Engineered for off-road racing, this helmet balances superior ventilation and comfort in an ultralight design while a highly aerodynamic composite shell delivers exceptional impact protection.

• A-head fitment and visor detaching system with PLASMA technology at the lower shell edge to optimize energy dissipation near the collar bone area.
• Aerodynamic profile promotes smooth deflection to reduce friction and efficiently transfer impact energy away from the head and neck.
• Ultra-ventilated: 20 intake and exhaust ports (13 intakes, 7 exhausts) for optimum airflow.
• Customizable fit via replacement cheek pads available in multiple thicknesses and interchangeable across shell sizes.
• Communication system compatible with a left-side EPS cutaway and earphone recesses on both sides.

Construction: linings are removable and washable by hand using warm water and neutral soap; fabrics feature antimicrobial treatments. Crown and neck pads are elastically connected for improved oblique impact management. The top pad is removable and height-adjustable via the A-head system. Cheek pads use 3D foam, include an emergency extraction system (ERS), and offer a channel for hydration tube installation. The chin strap features a 25 mm nylon strap with stainless steel DD rings and removable covers for washing. Integrated channels on both sides accommodate a hydration system.

Protection: the visor detaching system is engineered to automatically release under impact energies greater than 15 Joules to avoid anchoring weaknesses, while PLASMA inserts in the side pads provide strategic shock absorption in critical areas.

Materials: engineered mix of fiberglass, EPS, polyurethane, polypropylene, PVC, steel, polyamide, ABS, and polyester components designed for performance and safety.
