It wasn't easy to improve upon the class-leading design and function of the D3 helmet, but Troy Lee Designs made it happen. Built with an aerospace shell design and materials, they were able to get the D4 Composite helmet to 1050 grams without sacrificing any strength. 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.
