Features

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.
  • Aerospace composite shell, Lightest Composite DH/BMX Race helmet we have ever built 1050g (+/- 50g and Size M)
  • MIPS C2, 24 total vents: 10 front intake ports, 5 overhead intake vents that channel air on top of your head and an industry leading 7 rear exhaust ports
  • 3 Shell sizes and 3 EPS sizes, 6 total size ranges from XS-XXL, /Quick Dry XT2 Quick release contoured 3D cheek pads create an anatomically optimized fit. Separately placed X-Static & XT2 precision fit headliner with 7 anchor points gives you optimal fit
  • EPP Collarbone impact system; a relief area reduces the forces in the center lower section of the helmet where shoulder/collarbone impacts have been known to occur
