THE ARTEX MIPS HELMET IS READY FOR RIDING TRAILS AND GRINDING OUT LONG MILES ON MIXED SURFACE ROADS. The fit is luxurious and secure, thanks to our highly-adjustable Roc Loc 5 Air MIPS system that allows you to customize fit/feel for great stability and long-range comfort while providing an added measure of protection from rotational forces in the event of an angled impact. The outer shell is molded from a tough polycarbonate that's fused permanently to the EPS foam liner using our In-Molding construction process to enhance durability and ventilation without excess bulk.
