Alpinestars S-M7 Deed Helmet — Size S, A-Head fitment

Engineered for off-roading racing, this helmet balances superior ventilation and comfort in a lightweight design while a supremely aerodynamic composite shell delivers exceptional impact protection.

Featuring A-Head fitment and a visor detaching system, it incorporates PLASMA technology along the lower shell edge to optimize energy dissipation in collisions near the collar bone.

The aerodynamic profile promotes smooth shell deflection to reduce friction on impact and efficiently transfer energy away from the rider's head and neck.

Ultra-ventilated with 20 intake and exhaust ports—13 intakes and 7 exhausts—this helmet maintains airflow for extended riding sessions.

Removable, washable linings and three-dimensional cheek pads with an emergency extraction system allow personalized fit and easy maintenance, while cheek pads are interchangeable across sizes.

Communication-ready with a cutaway in the EPS for intercom systems and earphone recesses on both sides, plus integrated channels to accommodate a hydration system.

The visor detaching mechanism is engineered to release automatically under impact energies above 15 joules, and PLASMA inserts provide strategic shock absorption for critical side impacts.

Construction combines impact-absorbing components and supportive materials for a balance of protection, comfort and functional features designed for off-road performance.
