Product details

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.

  • MIPS brain protection system
  • UD carbon fiber shell
  • Three shell sizes to better fit various head sizes and age groups of riders
  • Anatomically shaped "3D" cheek pads with emergency release system for rescue services
  • Removable, snap-in, washable comfort liner with Coolmax® and moisture-wicking Dri-lex® materials
  • Extremely lightweight titanium D-rings
  • 1000 grams
  • CPSC 1203, CE EN1078, ASTM F1952-DH, ASTM 2032-BMX. Varies according to regional standards.
