Alpinestars SM5 Action ECE MX Helmet

The all-new Alpinestars SM5 Action ECE MX helmet is the result of more than five years of intensive study, development and testing. Alpinestars scrutinized every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort. This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight, while the five-density EPS liner ensures the correct density in the correct area for enhanced impact absorption.

Features:
• The lightweight outer shell is constructed from advanced impact-resistant thermoplastic in two sizes
• Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption
• A patented visor release system ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact
• Multi-air inlets and exhaust ports
• Weight from: 1250g +/-50g
• The SM5 helmet conforms to both DOT certification and ECE homologation for use worldwide
