Alpinestars SM5 Solid Helmet Black Matt Medium 8303123-110-M

The Alpinestars SM5 Solid Helmet in Black Matt combines a lightweight, impact-resistant thermoplastic outer shell with advanced construction designed for rider protection and comfort. Its visor directs air into the helmet ports to enhance airflow, while multiple air inlets and exhaust ports maximize ventilation and heat transfer exchange.

The helmet features multi-density inner liner materials to provide the correct density in designated areas for enhanced impact absorption. Its inner and outer surfaces are engineered to minimize the effects of oblique impacts, and the side shell paired with soft EPS foam helps prevent collarbone damage in the event of a crash. A patented visor release system is designed to release the visor with a predetermined amount of force, regardless of impact angle.

Convenience features include integrated hydration tube channels in the cheek pads, removable cheek pads with an emergency release system, and 3D-contoured foam for rider comfort. The removable comfort liner uses SILVERPLUS®-treated antibacterial fabric to wick moisture away from the skin, and the anti-microbial liner is removable and washable. Stainless steel D-rings provide a tight, secure fit. The Alpinestars SM5 conforms to DOT certification and ECE homologation for worldwide use. Product part number: 8303123-110-M.
