Troy Lee Designs D4 Carbon MIPS Helm

It wasn't easy to improve the leading design and functionality of our D3 helmet, but we succeeded. With aerospace design and materials, we were able to reduce the D4 Composite helmet to 1050 grams without compromising strength. The MIPS C2 protection system is used to add an extra layer of safety in the event of a fall. For comfort, the D4 Comp channels cool air through a front air intake system that flows through the polymer central and Power Grid side mesh, keeping the head cooler while riding. X-static® and XT2® antimicrobial/odor-resistant padding ensures that the inside of the helmet is a more pleasant place.
