Alpinestars SM5 Solid Helmet Black Matt Large 8303123-110-L

The Alpinestars SM5 Solid Helmet in Black Matt, Large, combines a lightweight impact-resistant thermoplastic outer shell with advanced ventilation and impact-management features. The visor is designed to direct air into the helmet’s ports, while multiple air inlets and exhaust ports help maximize ventilation and heat-transfer exchange.

Engineered inner and outer surfaces help minimize the effects of oblique impacts. A multiple-density inner liner places the appropriate density in each area for enhanced impact absorption, while the side shell and soft EPS foam are designed to help prevent collarbone damage in a crash. The helmet also features a 26 mm soft textile chin strap and stainless steel D-rings for a tight, secure fit.

Convenience and emergency-removal features include integrated hydration tube channels in the cheek pads, removable cheek pads, and an emergency release system that permits safe, easy cheek-pad removal while the helmet remains on. Three-dimensionally 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 removable comfort liner uses SILVERPLUS®-treated antibacterial fabric to wick moisture away from the skin. The antimicrobial liner is removable and washable. The SM5 conforms to DOT certification and ECE homologation for worldwide use. The Alpinestars part number is 8303123-110-L, and the SKU is 482-9222L.
