Expertly designed for elite off-road racing, the S-M7 Deed Helmet delivers a superior blend of ventilation and impact protection in a lightweight composite shell. Featuring Alpinestars' patented A-Head Fitment System and PLASMA technology for critical energy dissipation, it exceeds ECE 22.06 rotational standards by 76%. Includes: hydration system compatibility and a crash-responsive patented visor release system.

Key features

Aerodynamic Design: Smooth, streamlined shell profile eliminates external channels that could act as load points, preserving structural integrity during impact.
Energy-Deflecting Design: Engineered curved shell reduces friction and deflects impact forces away from the head to protect the skull, neck, and spine.
PLASMA Inside: Patented PLASMA technology integrated into side pads provides high-performance shock absorption in critical areas to significantly reduce injury risk.
A-Head Technology: Patented A-Head Fitment System allows for precise adjustment of the helmet's angle and height for a customized, optimized performance fit.
Patented Visor Release: Designed to detach automatically when subjected to impact energy greater than 15 Joules, reducing rotational injury risk regardless of impact direction.
Shell Sizing for Optimal Fit: Available in 3 shell sizes and 6 consumer sizes (XS-XXL) to ensure an anatomical fit that improves comfort, reduces weight, and maximizes impact effectiveness.
Hydration System Ready: Features integrated internal channels on both sides to easily accommodate hydration system plumbing.

Protection

Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber for the optimum blend of 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 ventilation.
Eject Removal System Ready: the helmet is designed to accommodate the installation of an eject removal system, which includes a removable insert on top of the EPS.
Removable lining: With a 3D foam for optimum comfort, the lining features an anti-microbial treatment for long-lasting freshness.
The S-M7's fit can be further customized via the Alpinestars genuine replacement cheek pads, which are available in all thicknesses, and are exchangeable between all shell sizes.
Lightweight: ECE 1280g and DOT 1340g for a size medium.
The S-M7 is available in 2 versions: ECE 22.06 and DOT homologation standards.

Construction

Shell construction utilizes highly advanced molding technology with pre-preg composite construction for enhanced mechanical performance and ultra-light weight.
Unique shell lay-up process results in extremely effective impact protection, with linear and oblique impact performance significantly exceeding current regulatory standards.
Specific rotational impact protection provided by the internal shape and specific coating of the EPS liner, coupled with a specially-developed surface in the comfort liner.
Alpinestars Patented Specific Coating technology reduces rotational acceleration transmitted to the head, exceeding the ECE 22.06 Peak Rotational Acceleration standard by 76%.
Profiled chin bar engineered for proven impact protection.
