Alpinestars S-M7 Deed Helmet — Size L, Blue

Engineered for off-roading racing, the S-M7 Deed Helmet balances superior ventilation and comfort in a lightweight design, while a supremely aerodynamic composite shell delivers exceptional impact protection. 🚵‍♂️

Advanced fit and protection:

• A-Head fitment and visor detaching system with PLASMA technology at the lower shell edge to optimize energy dissipation around the collar bone.
• Visor designed to automatically detach when subjected to impact energy greater than 15 joules to reduce transfer of force.
• Shell curvature promotes deflection, reducing friction on impact and enabling efficient energy transfer away from the head and neck.

Ventilation and comfort:

• Ultra-ventilated design with 20 intake and exhaust ports (13 intakes, 7 exhausts) for optimum airflow.
• Top pad is removable and adjustable in height via the A-head system; crown and neck pads are elastically connected for improved oblique impact management.
• Removable, washable linings with antimicrobial treatments; cheek pads use 3D foam with an emergency extraction system and a channel for hydration tube installation.

Compatibility and convenience:

• Communication system compatible thanks to a cutaway section on the left-side EPS and earphone recesses on both sides.
• Integrated channels on both sides accommodate a hydration system; chin strap features stainless steel DD rings and removable covers for washing.

Construction and materials:

• Strategically integrated PLASMA side pads provide high-performance shock absorption in critical areas. 🛡️
• Multi-material construction and engineered components deliver durable protection and reliable impact management.
