AlpinestarsS-M7 Cast Helmet Blue

Engineered for off-roading racing, and is optimized to offer the perfect blend of superior ventilation and comfort in a lightweight, helmet while its supremely aerodynamic composite shell delivers exceptional impact protection

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 collar bone area

Key Features

Aerodynamic profile design offers a smooth, streamlined shell free of any 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 referred 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 the Alpinestars replacement cheek pads, which are available in all thicknesses and are exchangeable between all shell sizes

Communication System Compatible — Cutaway section on the left-side of the EPS to seamlessly accommodate Intercom Systems, with earphone recesses on both sides for speakers

Construction

Linings are removable and washable by hand 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 adjustable in height thanks to the A-head system

Cheek Pads — The cheek pads are fitted 3D foam, with an emergency extraction system (ERS), with a channel for hydration tube installation

Cheek pads are interchangeable among all sizes

Chin Strap — Chin strap is fitted with a 25 mm width nylon strap, stainless steel DD rings, removable covers for washing purpose

Integrated channels on both sides to accommodate a hydration system

Protection

Visor Detaching System features a release mechanism is conceived to avoid the inherent weaknesses in other anchoring systems

Visor is engineered to automatically detach from the shell when it is subjected to an impact energy greater than 15 Joules for optimum impact protection, regardless of the direction

PLASMA inside
Alpinestars PLASMA technology is strategically-integrated into the S-M7's side pads for high performance shock absorption in a critical area, significantly reducing risk of injuries
