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. Riders like Sam Hill, Aaron Gwin, Steve Peat, Brandon Semenuk and Cam Zink refuse to wear anything else when they pedal.
