Troy Lee Designs D4 Composite Full Face Helmet for Adults

Designed and intended exclusively for bicycling activities, including mountain biking and off-road cycling, this helmet is built with an aerospace shell design and materials, allowing us to achieve a weight of 1050 grams without compromising strength. To add an additional layer of safety in the event of a fall, the MIPS C2 protection system is utilized. Featuring 20 high-flow intake and exhaust ports for maximum ventilation, the helmet also incorporates added EPS and a new headform shape for improved impact performance. For emergency helmet removal, it includes a MIPS quick-release and contoured 3D cheek pads. The removable snap-in washable comfort liner is made with Coolmax and Dri-lex moisture-wicking materials, while the super light titanium D-rings save weight and offer increased material tensile strength.

Certified to CPSC 1203, CE EN1078, ASTM F1952-DH, and ASTM 2032-BMX standards, this helmet is a product of Troy Lee Designs, a company with 40 years of racing experience catering to the World's Fastest Racers.
