It wasn't easy to improve upon the class-leading design and function of our D3 helmet, but we made it happen. Built with an aerospace shell design and materials, we were able to get the D4 Composite helmet down 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 Composite helmet routes cooling air through a front air intake system that flows through the polymer centre and power grid side mesh keeping your head cooler during the ride. X-static® and XT2® anti-microbial/anti-odour padding keep the inside of the helmet a much nicer place to be.
