ALPINESTARS SM5 Solid Helmet White Glossy Medium, SKU 482-9223M

The ALPINESTARS SM5 Solid Helmet in White Glossy is designed for protective performance, ventilation, and rider comfort. Its lightweight outer shell is made from impact-resistant thermoplastic and is available in two shell sizes. The visor directs air into the helmet’s ports to support airflow, while multiple air inlets and exhaust ports help maximize ventilation and heat transfer.

Engineered inner and outer surfaces help minimize the effects of oblique impacts. A multi-density inner liner places the appropriate density in specific areas to support impact absorption, 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 for added comfort and safety, and stainless steel D-rings help provide a secure fit.

The helmet includes an emergency release system and removable cheek pads for easier removal while the helmet remains on. Three-dimensionally contoured foam supports 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, and the antimicrobial liner is removable and washable.

The ALPINESTARS SM5 conforms to DOT certification and ECE homologation for worldwide use. A size Medium weighs 1,370 g according to the DOT specification. This product is identified by SKU 482-9223M and part number 8303123-2180-M.
