Alpinestars SM5 Solid Helmet White Glossy Medium, SKU 482-9201M

The Alpinestars SM5 Solid Helmet in White Glossy is designed for riders seeking impact protection, ventilation, comfort, and convenient helmet removal features. Its lightweight outer shell uses impact-resistant thermoplastic construction in two shell sizes, while the inner and outer surfaces are engineered to help minimize the effects of oblique impacts.

Airflow is supported by a visor designed to direct air into the helmet’s ports, along with multiple air inlets and exhaust ports for ventilation and heat-transfer exchange. Integrated hydration tube channels in the cheek pads add convenience, while the side shell and soft EPS foam are designed to help prevent collarbone damage in a crash. The 26 mm soft textile chin strap is wider than certification requirements and uses stainless steel D-rings for a secure fit.

The helmet features a multiple-density inner liner for impact absorption in designated areas, plus a patented visor release system engineered to release the visor with a predetermined amount of force regardless of impact angle. An emergency release system and removable cheek pads allow the cheek pads to be removed while the helmet remains on. The removable comfort liner uses SILVERPLUS® treated antibacterial fabric for moisture wicking, and the antimicrobial liner is removable and washable.

This Alpinestars helmet conforms to DOT certification and ECE homologation for worldwide use. A size Medium weighs 1,370 g according to the DOT specification. SKU: 482-9201M. Part number: 8303121-2180-M.
