The Alpinestars SM3 Helmet in Heat Gloss White/Purple/Pink, size 2XL, is engineered for riders seeking optimal protection, comfort, and performance in motocross, enduro, and offroad applications. Its shell features a varied thickness construction with a thermo-injected polymer blend that combines impact resistance and lightweight design. The impact-resistant thermoplastic outer shell is complemented by an inner composite fiber layer positioned between the outer shell and EPS liner, ensuring maximum impact absorption without adding excess weight. The helmet's fit can be precisely tailored with adjustable crown and cheek pads for a secure and comfortable ride.
The multiple density EPS liner system, comprising a 6-piece design with five different foam densities, optimizes impact management by distributing forces across targeted areas. Its polished surface, coated to reduce friction, works in tandem with the comfort liner to mitigate rotational impacts, enhancing rider safety. The helmet is equipped with an advanced ventilation system featuring ten air inlets and seven exhaust ports, with the visor designed to channel airflow into these ports for effective heat dissipation during intense riding. The visor release system is calibrated to release with a predetermined force, reducing neck strain during impacts.
Sustainability is addressed with the use of recycled materials in the comfort liner, while integrated hydration channels in the cheek pads offer convenience during demanding rides. The soft textile chin strap provides a secure fit and rider comfort, while the inclusion of stainless steel D-rings ensures a firm connection. Safety features include an Emergency Release System and removable cheek pads, allowing for quick and safe helmet removal if necessary. The helmet's chin area is optimized for superior impact performance, and the design incorporates a low-friction coating on the EPS liner to minimize rotational accelerations caused by oblique impacts. Overall, the Alpinestars SM3 helmet combines advanced impact protection, ventilation, and comfort to meet the demands of serious offroad enthusiasts.
