D4 Composite MIPS
Always evolving. Built with an aerospace shell design and materials, the D4 Composite comes in at just 1050 grams without sacrificing any strength. Mips C2 protection adds an additional layer of safety in the event of a fall, while a front air intake system -- flowing through a polymer center and power grid side mesh -- routes cooling air to keep 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. Full incremental sizing, quick-release cheek pads with emergency removal, and purpose-built audio cavities make the D4 Composite as liveable as it is capable.
