Helmet ALPINESTARS S-M7 Core

• Engineered for off-road racing, offering the ideal blend of superior ventilation and comfort in a lightweight helmet, while its highly aerodynamic composite shell delivers exceptional impact protection
• Featuring the A-Head Fitment and Visor Detaching System, the S-M7 is equipped with PLASMA technology at the lower side of the shell edge for optimum energy dissipation in case of contact with the collarbone area
• Key Features
• Aerodynamic profile design offers a smooth, streamlined shell free of external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet's construction
• The shell's curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider's head from direct force and force transferred to the neck and spinal column
• Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum ventilation
• The fit can be further customized via Alpinestars replacement cheek pads, available in all thicknesses and interchangeable between all shell sizes
• Communication System Compatible — Cutaway section on the left side of the EPS accommodates Intercom Systems, with earphone recesses on both sides for speakers
• Construction
• Linings are removable and hand washable using warm water and neutral soap
• Fabrics have antimicrobial treatments
• Crown Pad — Crown pad and neck pad are elastically connected for better oblique impact management
• Top Pad — The top pad is removable and height-adjustable thanks to the A-head system
• Cheek Pads — The cheek pads are made of 3D foam, with an emergency extraction system (ERS) and a channel for hydration tube installation
• Cheek pads are interchangeable among all sizes
• Chin Strap — Fitted with a 25 mm wide nylon strap, stainless steel DD rings, and removable covers for washing
• Integrated channels on both sides accommodate a hydration system
• Protection
• The Visor Detaching System features a release mechanism designed to avoid the inherent weaknesses of other anchoring systems
• The visor is engineered to automatically detach from the shell when subjected to impact energy greater than 15 Joules for optimum impact protection, regardless of direction
• PLASMA inside; Alpinestars PLASMA technology is strategically integrated into the S-M7 side pads for high-performance shock absorption in a critical area, significantly reducing the risk of injuries
