White/Grey/Silver Sz XS Alpinestars SM5 Rayon Helmet (8304121-928-XS)

The SM5 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 light weight, while the five density EPS (Expanded Polystyrene) liner ensures the correct density in the correct area for enhanced impact absorption. Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in two sizesMultiple density inner liner to ensure the correct density in the correct area for enhanced impact absorptionSide shell coupled with soft EPS foam prevents damage to collarbone in the event of a crashInner and outer surfaces are engineered to minimize the effects of oblique impactsMaximized ventilation and high levels of heat transfer exchange thanks to multi air inlets and exhaust portsVisor has been designed to direct air into the ports for enhanced airflowPatented visor release system ensures the visor is released with the correct predetermined amount of force, irrespective of the angle of impactEmergency Release System
