A sleek shell sees improvements to venting and better goggle compatibility as well as a magnetic buckle to make fitment easy.What hasn't changed is the superb level of protection. In the event of a crash, the EPS foam core provides shock absorption, helping to prevent injury. This protective core is fused to a durable polycarbonate shell. In combination with the inner, this system offers reliable protection against minor dings from trailside overgrowth as well as more serious impacts.  MIPS (Multi-directional Impact Protection System)Made to meet and exceed international standards, Bell also turn to MIPS to add an extra layer of head protection to their 4Forty Air. This split-plane technology gives an extra level of brain-protecting technology, designed to redirect energy and provide more protection in certain impacts.This system is integrated into the fit system, reducing weight, simplifying the design and optimising ventilation. • MIPS is a Brain Protection System• Rotational motion can cause brain injuries• The low friction layer allows a sliding movement of 10–15 mm, in all directions, reducing rotational motion to the brain during impact• MIPS adds protectionFeature-packed MTB PerformanceWhen you're in the flow of the trail or grinding it up a steep uphill, 14 large vents let air rush over your head so you don't overheat.
