Alpinestars SM3 Helmet - Heat, Gloss White/Purple/Pink, Medium - Part 8301026-2052-M

The Alpinestars SM3 Helmet is engineered for offroad and motocross enthusiasts seeking optimal protection combined with lightweight comfort. Featuring a thermo-injected shell with varied thickness layers, this helmet provides superior impact resistance while maintaining a low weight profile, making it ideal for demanding MX, Enduro, and offroad riding. The impact-resistant outer shell is constructed from durable thermoplastic, while the inner shell incorporates a composite fiber layer sandwiched between the outer shell and EPS liner for enhanced impact absorption and durability. The helmet’s fit can be customized to the rider’s head shape through adjustable crown and cheek pads, ensuring a secure and comfortable fit for extended wear. The multi-density inner liner utilizes five different foam densities to effectively manage impact forces and reduce overall weight, supported by a polished, low-friction coating that minimizes rotational injuries during oblique impacts. The helmet also features a six-piece EPS liner with specialized coatings designed to maximize impact dispersion and heat transfer, keeping the rider cool under strenuous conditions. Ventilation is a key feature, with ten intake vents and seven exhaust ports that facilitate maximum airflow, while the visor is engineered to channel air into these ports for enhanced cooling efficiency. The visor release system is calibrated to detach under specific force levels, reducing neck strain during impacts. Comfort is further enhanced by recycled material-based liners and integrated hydration channels in the cheek pads for convenience. The soft, 25 mm textile chin strap ensures a secure fit, and the helmet includes an emergency release system with removable cheek pads for safe, easy removal. The chin area is specially designed for superior impact performance, and stainless steel D-rings provide a reliable, secure fastening. This helmet is not only built for protection but also incorporates thoughtful features like a 3D contoured foam for comfort and a ventilation system that promotes heat regulation, making it a comprehensive choice for offroad riders who demand safety, performance, and comfort.
