Alpinestars SM3 Helmet - Heat Gloss Red/White/Black, Medium (Part #8301026-3126-M)

The Alpinestars SM3 Helmet offers a high level of protection and comfort designed specifically for motocross, enduro, and offroad riders. Featuring a thermo-injected shell with varied thickness, this helmet optimizes impact absorption while maintaining a lightweight profile. The impact-resistant thermoplastic outer shell is complemented by an inner composite fiber layer and a multi-density EPS liner, providing tailored protection that effectively manages different types of impacts. The six-piece EPS liner with five densities enhances impact performance while reducing overall weight, ensuring riders stay comfortable during extended rides. The polished inner liner, coated to reduce friction, works in conjunction with a comfort liner to help manage rotational impacts, minimizing the risk of injury during oblique crashes. Ventilation is maximized through ten inlet vents and seven exhaust ports, with the visor designed to direct airflow into these ports for superior cooling. A visor release system ensures safety by releasing with a predetermined force, reducing strain on the rider's neck in the event of an impact. The helmet also features a recycled material comfort liner, providing a sustainable option without compromising performance. Integrated hydration tube channels in the cheek pads add convenience for riders who need quick access to water during intense offroad sessions. The soft textile chin strap ensures a snug and comfortable fit, while the stainless steel D-rings guarantee a secure closure. Safety is further enhanced with an Emergency Release System and removable cheek pads for easy and safe removal, even while the helmet is worn. The chin area is specially contoured for superior impact performance, and the helmet’s design incorporates a low-friction coating on the EPS liner to reduce rotational forces during oblique impacts. The overall construction and features of the Alpinestars SM3 Helmet make it an ideal choice for riders demanding performance, protection, and comfort on the trails and tracks.
