Alpinestars S-M7 Dasher Helmet — 2XL, Black

Engineered for off‑road racing, this lightweight helmet blends superior ventilation and comfort with a supremely aerodynamic composite shell for exceptional impact protection.

The helmet features an A-head fitment and a visor detaching system, and is equipped with PLASMA technology at the lower side of the shell edge for optimized energy dissipation in case of contact with the collar bone area.

An aerodynamic profile offers a smooth, streamlined shell free of external channels or protrusions that could act as load points, while the shell curvature promotes reduced friction on impact to allow deflection and efficient energy transfer away from the head and neck.

Ultra-ventilated design with 20 intake and exhaust ports (13 intakes and 7 exhausts) delivers optimum airflow and cooling for high-exertion riding.

Customizable fit via interchangeable cheek pads available in multiple thicknesses, a removable and height-adjustable top pad through the A-head system, and a crown pad elastically connected to the neck pad for improved oblique impact management. Cheek pads include an emergency removal system and a channel for hydration tube installation.

Linings are removable and washable by hand with warm water and neutral soap, and fabrics are treated with antimicrobial finishes for long-lasting freshness.

Integrated channels and a left-side EPS cutaway accommodate communication systems, with earphone recesses on both sides for speaker placement.

The visor detaching mechanism is engineered to avoid weak anchoring points and is designed to automatically release from the shell when subjected to impact energy above 15 joules, improving impact protection regardless of direction. PLASMA inserts at the sides provide high-performance shock absorption in a critical area to reduce injury risk.
