Alpinestars S-M5 Action Helmet

The Alpinestars S-M5 is crafted with a lightweight thermoplastic outer shell in two sizes, it ensures impact resistance while optimizing comfort. The innovative visor design enhances airflow through dedicated ports. Stay hydrated easily with integrated hydration tube channels in the cheek pads. Its engineered surfaces minimize oblique impact effects, while the side shell and EPS foam combo shield the collarbone during crashes. Safety is paramount with the wider-than-required textile chin strap and multiple-density inner liner for optimal impact absorption. The emergency release system and removable cheek pads enhance convenience and comfort, while the patented visor release system guarantees controlled visor detachment.

Stay fresh with the SILVERPLUS treated anti-bacterial fabrics that wick moisture away, and enjoy a secure fit with stainless steel D-rings.
