ALPINESTARS Motocross Helm SM3 Solid

The SM3 helmet was developed for MX, enduro and off-road riders and combines state-of-the-art materials with innovative technology for maximum protection and comfort.
The thermo-injected shell made from a special polymer mixture offers the perfect balance of lightness and impact protection. An advanced ventilation system with 10 inlets and 7 outlets ensures optimal air circulation and a comfortable helmet climate.
Thanks to the patented low-friction coating in the EPS liner, rotational forces are effectively reduced in the event of oblique impacts. The visor release system detaches with precisely defined force, minimising stress on the neck in the event of a fall.
Multi-layer EPS protection, hydration channels in the cheek pads and an inner lining made from recycled materials ensure individual comfort. The emergency removal system, 25 mm wide chin strap and stainless steel D-rings guarantee maximum safety.
The Alpinestars Motocross Helmet meets both ECE 22.06 homologation and DOT certification requirements – for worldwide approval and uncompromising safety.
