The Alpinestars SM3 Heat Helmet is designed for motocross, enduro, and off-road riding, delivering a balanced combination of impact protection, lightweight performance, and rider comfort. This Small helmet features a gloss red, white, and black Heat graphic finish and uses a thermo-injected polymer shell engineered with varied thicknesses for optimized protection in key impact areas.
The helmet's lightweight thermoplastic outer shell works with a composite fiber layer and a six-piece, multi-density EPS liner to manage impact energy effectively. The polished EPS surface and low-friction coating are designed to help reduce rotational acceleration during certain oblique impacts. The crown and cheek pads can be tailored to the rider's head for a secure, comfortable fit, while the 3D-contoured cheek pad foam supports comfort during extended rides.
Ten intake vents and seven exhaust ports promote airflow and heat transfer, with the visor designed to direct air toward the ventilation openings. The visor release system is engineered to release at a predetermined force to help reduce loads on the rider's neck during an impact. Recycled materials are used in the comfort liner, and integrated hydration tube channels in the cheek pads provide added convenience for off-road riding. A soft 25 mm chin strap and stainless steel D-rings help provide a secure fit.
For added protection and emergency response, the Alpinestars SM3 includes an Emergency Release System and removable cheek pads that allow the pads to be removed while the helmet remains in place.
