Troy Lee Designs D3 Fiberlite Mono Adult BMX Helmet

It wasn't easy to improve upon the class-leading design and function of our D2 helmet, but we made it happen. By integrating next-level safety devices and making functional improvements, we raised the bar for head protection in the genre with our D3. The only helmet to win Olympic BMX Gold, World Cup DH Series Gold and Redbull Rampage Gold!
Riders like Brendan Fairclough, Aaron Gwin, Steve Peat, Brandon Semenuk, Cam Zink, Luca Shaw, Sam Willoughby, Alise Post and Mariana Pajon refuse to wear anything else when they pedal. With styles and colors to fit any personality, the only question is: Which one is for you?.
