SM3 Helmet - Radium - Matte Gray/Black/Yellow Fluo - XL
The Alpinestars SM3 Helmet Radium offers advanced protection and comfort designed specifically for motocross, enduro, and offroad riding. Featuring a thermo-injected shell with varied thicknesses, this helmet balances impact resistance with lightweight performance, ensuring optimal safety without sacrificing agility. The impact-resistant outer shell is crafted from durable thermoplastic, while the inner shell incorporates a composite fiber layer sandwiched between the outer shell and EPS liner for maximum impact absorption. The helmet's fit can be customized using adjustable crown and cheek pads, providing a secure and comfortable fit tailored to individual rider preferences.
The multiple density EPS liner system employs five different foam densities to effectively manage impact forces and reduce overall weight. The polished inner EPS liner is coated to minimize friction, enhancing rotational impact management and reducing the risk of injury during oblique impacts. Additionally, the helmet's surfaces are engineered to mitigate the effects of angled impacts, further enhancing rider safety. Ventilation is prioritized with ten inlet and seven exhaust ports, complemented by a visor designed to channel airflow into these ports, keeping the rider cool during intense activity. The visor release system is engineered to detach with controlled force, reducing strain on the rider*s neck in the event of an impact.
Constructed with environmentally conscious materials, the comfort liner is made from recycled textiles, aligning safety with eco-friendly practices. Integrated hydration channels within the cheek pads offer added convenience for riders during long sessions. The soft textile chin strap, measuring 25 mm, ensures a snug and comfortable fit, providing essential safety during high-impact situations. Safety features include an emergency release system and removable cheek pads for quick and safe helmet removal, even when the rider is still wearing the helmet. The 3D contoured foam padding enhances comfort throughout extended use, while the chin area is optimized for superior impact performance. Stainless steel D-rings secure the helmet firmly in place, delivering a reliable fit for demanding offroad conditions.
