The all-new SM5 helmet is the result of more than five years of intensive study, development and testing. We 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 protection and light weight, while the five density EPS liner ensures the correct density in the correct area for enhanced absorption. Lightweight outer shell is constructed. The inner and outer surfaces are engineered. Multiple density inner liner to ensure the correct density. Patented visor release system ensures the visor is released with the correct pre-determined amount of force. DOT approved, meets FMVSS 218 standard. Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.. The visor has been designed to direct air into the ports for enhanced airflow.. Stainless steel D-rings to ensure a tight and secure fit.. A size Medium weighs 1260g (ECE) 1380g (DOT).. The SM5 helmet conforms to both DOT certification and ECE homologation for use worldwide.. Emergency release system and removable cheek pads permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort. Liner is removable and washable.. Hydration tube channels are integrated into the helmet's cheek pads for convenience and performance.. Soft textile chin strap is 26mm and is wider than certification requirements for optimal safety and rider comfort.
