Alpinestars SM3 Heat ECE06/DOT Motorcycle Helmets

The Alpinestars SM3 is engineered for the rigors of MX, Enduro, and off-road riding. It integrates advanced technologies and design innovations to deliver a perfect balance of comfort, ease of use, and superior impact protection for riders of all levels.

Advanced Shell Construction

• Thermo-Injected Shell: Crafted from a specialized polymer blend with varying degrees of thickness to optimize the balance between impact resistance and weight.

• 4-Density EPS Liner: Features a 5-piece inner EPS assembly with 4 distinct densities to manage volume and energy absorption precisely.

• Optimized Chin Bar: Shell thickness and structure have been reinforced at the chin area to pass Alpinestars' strict internal testing, exceeding standard homologation requirements.

• Lightweight Design: The ECE version weighs approximately 1,430g, while the DOT version weighs 1,460g (Size Medium).

Rotational & Neck Protection

• Patented Low-Friction Coating: Applied to the main EPS liner, this layer acts as a "slip plane" to mimic the brain’s natural defenses, significantly reducing rotational acceleration forces.

• Smart Visor Release System: The patented release mechanism ensures the visor detaches with a pre-determined amount of force, protecting the rider's neck from strain during an impact.

• Oblique Impact Mitigation: Both inner and outer surfaces are specifically engineered to minimize the dangerous effects of angled or oblique impacts.

Maximized Ventilation & Comfort

• High-Flow Cooling: Features 10 air inlets and 7 exhaust ports to maximize heat transfer exchange and keep the rider cool in intense conditions.

• Integrated Hydration Channels: Channels are built directly into the cheek pads for the seamless integration of a hydration tube.

• Eco-Friendly Liner: The comfort liner is constructed using recycled materials, reducing the helmet's carbon footprint without compromising performance.

• Customizable Fit: Tailor your comfort with crown and cheek pads available in various thicknesses as genuine spare parts.

Professional Safety Features

• Emergency Release System (ERS): Allows for the safe and easy removal of cheek pads by medical personnel while the helmet is still being worn.

• Secure Fastening: Equipped with a 25mm soft textile chin strap and durable stainless steel D-rings for a tight, reliable fit.

• 3D Contoured Foam: Ensures an ergonomic and snug fit that adapts to the rider's facial structure.
