Alpinestars S-M7 Deed Helmet

The S-M7 Helmet is engineered for off-road 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. As well as Alpinestars patented A-Head Fitment and Visor Detaching Systems, the S-M7 is equipped with innovative PLASMA technology at the lower side of the shell edge for optimum energy dissipation in case of contact with the collarbone area.

The S-M7’s 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 helmet’s curved shell is engineered to reduce friction and deflect impact forces away from the head, helping protect the skull, neck, and spine in the event of a crash. The S-M7 shell sizing solution ensures each helmet fit size delivers the most anatomical solution for the wide variety of fit needs worldwide, providing 3 different helmet shell sizes and 6 helmet sizes from XS to 2XL to ensure you have the correct fit which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact. 

Shell:

• Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber
• Energy-deflecting curved design is engineered to reduce friction and deflect impact forces away from the head
• 3 shell sizes
• Integrated channels on both sides to accommodate a hydration system

Visor:

• 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

Ventilation:

• 20 individual intake and exhaust ports, 13 intakes and 7 exhausts for optimum ventilation

Comfort:

• 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
• 3D foam for optimum comfort, the lining features an anti-microbial treatment for long-lasting freshness
• Replacement cheek pads are available in all thicknesses and exchangeable between all shell sizes for a customized fit

Safety:

• Specific rotational impact protection is provided by the combination of the internal shape and specific coating of the EPS liner, coupled to specially-developed surface in the comfort liner
• Patented Plasma technology in side pads provide high performance shock absorption 
• Helmet designed to accommodate the installation of an eject removal system, which includes a removable insert on top of the EPS
• Profiled chin bar for proven impact protection
