HOW TO MEASURE

Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, repeat for good measure and use the largest measurement.

Troy Lee D4 Composite Lowrider MIPS MTB Helmet

Always Evolving. Built with an aerospace shell design and materials, TLD 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 Composite 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.

Features:

  • With MIPS® C2 Rotational Impact Brain Protection System
  • 20 High-flow intake and exhaust ports for maximum ventilation
  • Added EPS and new head form shape for improved impact performance
  • Full incremental sizing for greater range of fitment
  • Strategically placed interior chinbar shock pads for comfort and durability
  • Quick-release and contoured 3D cheek pads for emergency helmet removal
  • Purpose-built internal cavities for audio integration
  • Stainless steel chinstrap D-rings are light and strong
  • Includes TLD drawstring helmet sock
  • Approx. 1050 g
  • Certifications: CPSC 1203, CE EN 1078:2002+A1:2012 ASTM F1952-15, ASTM F2032-15, ASTM F2040-11
