MIPS C2 protection system is used to add an additional layer of safety in the event of a fall. For comfort, the D4 Comp routes cooling air through a front air intake system that flows through the polymer center and power grid side mesh keeping your head cooler during the ride. X-static and XT2 anti-microbial/anti-odor padding keep the inside of the helmet a much nicer place to be. This helmet is designed and intended exclusively for use by bicycling activities, including mountain biking and off-road cycling.
