Alpinestars SM5 Solid Helmet Black Matte XL, SKU 482-9222X

The Alpinestars SM5 Solid Helmet in Black Matte, XL is designed with a lightweight outer shell made from impact-resistant thermoplastic. Its visor directs air into the helmet’s ventilation ports to support enhanced airflow, while multiple air inlets and exhaust ports help maximize ventilation and heat transfer.

Engineered safety features include inner and outer surfaces designed to minimize the effects of oblique impacts, a side shell coupled with soft EPS foam to help prevent collarbone damage during a crash, and a multiple-density inner liner designed to provide the appropriate density in different areas for impact absorption. The patented visor release system is designed to release the visor with a predetermined amount of force regardless of impact angle.

Comfort and convenience features include integrated hydration tube channels in the cheek pads, a removable comfort liner with SILVERPLUS® treated antibacterial fabric for moisture wicking, and a removable, washable antimicrobial liner. The emergency release system and removable cheek pads allow cheek pads to be removed while the helmet remains on, while 3D-contoured foam supports rider comfort. Stainless steel D-rings provide a secure fit, and the 26 mm soft textile chin strap is wider than certification requirements for rider comfort and safety.

The Alpinestars SM5 conforms to DOT certification and ECE homologation for worldwide use. A size Medium weighs 1,370 g under DOT specifications. This product is identified by SKU 482-9222X and part number 8303123-110-XL.
