Expertly designed for off-road racing, the S-M7 Solid Helmet is Alpinestars' high-performance solution for riders seeking superior ventilation and lightweight protection. Featuring a multi-layer composite shell and patented PLASMA technology, it delivers exceptional impact dissipation and exceeds ECE 22.06 rotational acceleration standards by 76%. The adjustable A-Head fitment system and 20-port ventilation network ensure optimized comfort and airflow for every ride.

Key features

Aerodynamic Design: Smooth, streamlined composite shell engineered without external channels to eliminate potential load points during impact and maintain structural integrity.
Energy-Deflecting Shell: Features a curved surface designed to reduce friction and deflect impact forces away from the head, protecting the skull, neck, and spine.
PLASMA Inside: Strategically integrated Alpinestars patented PLASMA technology in side pads provides high-performance shock absorption to reduce injury risk in critical areas.
A-Head Fitment System: Patented technology allows for precise adjustment of the helmet's height and angle on the head for a customized, optimized performance fit.
Patented Visor Release: Engineered to automatically detach when subjected to impact energy greater than 15 Joules, regardless of direction, to reduce rotational injury risks.
Anatomical Shell Sizing: Available in 3 shell sizes across 6 consumer sizes (XS-XXL) to ensure an accurate fit that improves comfort, reduces weight, and maximizes impact effectiveness.
Hydration System Ready: Incorporates dedicated internal channels on both sides of the shell to easily accommodate a hydration system tube.

Protection

Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber for optimum impact protection and force dissipation, sliding performance, energy absorption, stability, and durability.
Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head for an optimized performance fit.
Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum airflow.
Eject Removal System Ready: designed to accommodate the installation of an eject removal system with a removable insert on top of the EPS.
Removable Lining: features 3D foam for comfort and anti-microbial treatment for long-lasting freshness.
Customizable Fit: compatible with Alpinestars genuine replacement cheek pads in various thicknesses, exchangeable between all shell sizes.
Lightweight Performance: ECE version weighs 1280g (size Medium).
Certified Safety: Available in ECE 22.06 and DOT homologation standards.
