Lightweight Troy Lee Designs D4 Composite Mountain Bike Helmet for Adult Men Women

The D4 Composite helmet is the latest evolution in our class-leading design and function. Constructed with an aerospace-inspired shell and materials, we've managed to shave the weight down to 1050 grams without compromising strength. Featuring the MIPS C2 system, the D4 Comp provides an additional layer of protection.

For enhanced comfort, the helmet incorporates a front air intake system that channels cooling airflow through the polymer center and power grid side mesh, keeping your head refreshed during the ride. The interior benefits from X-static and XT2 padding, creating a more pleasant in-helmet experience. It's important to note that this helmet is not intended for use with motorized vehicles.

Maximizing ventilation, the D4 Comp boasts 20 high-flow intake and exhaust ports. We've also enhanced the impact performance through the addition of EPS and a refined headform shape. For emergency situations, the helmet offers a quick-release function and contoured 3D cheek pads for easy removal.

Comfort is further improved with a removable, snap-in, washable liner featuring Coolmax and Dri-lex moisture-wicking materials. To save weight without compromising strength, we've incorporated super-light titanium D-rings.

The D4 Composite helmet meets the CPSC 1203, CE EN1078, ASTM F1952-DH, and ASTM 2032-BMX safety standards, ensuring it's ready for the demands of the world's fastest racers.
