Alpinestars SM5 Solid Helmet Black Matte Medium, SKU 482-9200M

The Alpinestars SM5 Solid Helmet combines a lightweight, impact-resistant thermoplastic outer shell with advanced impact-management features for off-road riding. Its inner and outer surfaces are engineered to help minimize the effects of oblique impacts, while the multiple-density inner liner places the correct density in the appropriate area to support impact absorption. The side shell and soft EPS foam are designed to help prevent collarbone damage during a crash.

Ventilation is supported by multiple air inlets and exhaust ports, with a visor designed to direct airflow into the helmet’s ventilation ports. Integrated hydration tube channels in the cheek pads add convenience, while the removable comfort liner uses SILVERPLUS® treated antibacterial fabric to wick moisture away from the skin. The anti-microbial liner is removable and washable for easier maintenance.

Safety and convenience features include a soft textile chin strap, stainless steel D-rings for a secure fit, and an emergency release system with removable cheek pads for easier removal while the helmet remains on. Three-dimensional contoured foam supports rider comfort, and the patented visor release system is designed to release the visor with a predetermined amount of force regardless of impact angle. The Alpinestars SM5 conforms to DOT certification and ECE homologation for worldwide use. This product is SKU 482-9200M and part number 8303121-110-M.
