Lightweight MIPS Full Face Mountain Bike Helmet for Adults

Designed to Evolve: Enhancing the Class-Leading D3 Helmet

The journey to improve upon the acclaimed D3 helmet was no easy feat, but we at Troy Lee Designs were determined to push the boundaries of design and function. Crafted with an aerospace-inspired shell and cutting-edge materials, we proudly introduce the D4 Composite helmet, weighing in at a mere 1050 grams without compromising its strength.

Incorporating the MIPS C2 protection system, the D4 Comp offers an additional layer of safety, safeguarding the user in the event of a fall. For unparalleled comfort, the helmet features a front air intake system that channels cooling air through the polymer center and power grid side mesh, keeping your head refreshed during the ride.

To maintain a hygienic and odor-free environment, the D4 Comp is equipped with X-static® and XT2® anti-microbial/anti-odor padding, ensuring a pleasant experience for the rider. Designed and intended exclusively for bicycling activities, including mountain biking and off-road cycling, this helmet boasts 20 high-flow intake and exhaust ports for maximum ventilation.

Moreover, the D4 Comp incorporates enhanced EPS and a new headform shape, delivering improved impact performance. The quick-release and contoured 3D cheek pads facilitate emergency helmet removal, while the removable snap-in washable comfort liner, made with Coolmax and Dri-lex moisture-wicking materials, adds to the overall comfort.

Saving weight and increasing material tensile strength, the super-light titanium D-rings elevate the helmet's design. Adhering to the highest safety standards, the D4 Comp is certified under CPSC 1203, CE EN1078, ASTM F1952-DH, and ASTM 2032-BMX.

Embodying Troy Lee Designs' 40-year legacy of racing for the World's Fastest Racers, the D4 Composite helmet is a testament to our commitment to innovation, safety, and performance. Crafted in Corona, California, this helmet is a true reflection of our passion for the sport and our unwavering dedication to delivering exceptional products to our riders.
