Alpinestars SM5 Solid Glossy White Helmet Large | SKU 482-9223L

The Alpinestars SM5 Solid Glossy White Helmet in Large is designed with a lightweight, impact-resistant thermoplastic outer shell and advanced features for airflow, comfort, and impact management. Its visor directs air into the helmet’s ports, 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 side shell paired with soft EPS foam is designed to help prevent collarbone damage in a crash. The multiple-density inner liner places the appropriate density in each area for enhanced impact absorption, while the 26 mm soft textile chin strap provides a secure and comfortable fit with stainless steel D-rings.

The helmet includes integrated hydration tube channels in the cheek pads, removable cheek pads, and an emergency release system to support safe and easy cheek-pad removal while the helmet is still on. A patented visor release system releases the visor with a predetermined amount of force, regardless of impact angle. The removable comfort liner uses SILVERPLUS® treated antibacterial fabric for moisture wicking and is removable and washable. This helmet conforms to DOT certification and ECE homologation. SKU: 482-9223L. Part number: 8303123-2180-L.
