Alpinestars SM5 Solid Helmet Black Matt Small - 8303123-110-S

The Alpinestars SM5 Solid Helmet in Black Matt, part number 8303123-110-S, is designed with a lightweight outer shell constructed from impact-resistant thermoplastic in two shell sizes. Its visor directs air into the helmet ports to support airflow, while multiple air inlets and exhaust ports provide ventilation and heat-transfer exchange.

Engineered inner and outer surfaces help minimize the effects of oblique impacts. The side shell, combined with soft EPS foam, is designed to help prevent collarbone damage in a crash. A 26 mm soft textile chin strap is wider than certification requirements for rider safety and comfort, and stainless steel D-rings help provide a secure fit.

The helmet features a multiple-density inner liner for impact absorption, along with 3D-contoured foam for comfort. An emergency release system and removable cheek pads allow the cheek pads to be removed while the helmet remains on. 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 anti-microbial liner is removable and washable. The Alpinestars SM5 conforms to DOT certification and ECE homologation for worldwide use. A size Medium weighs 1,370 grams according to DOT specifications.
