Troy Lee Designs D3 Composite - 2018

The 2018 Troy Lee Designs D3 Composite Full Face Helmet. The benchmark full face helmet for MTB and BMX Race. Comes with a TLD helmet bag and a spare visor.

it wasn't easy to improve upon the class-leading design and function of the d2 helmet but troy lee designs made it happen. By integrating next-level safety devices and making functional improvements they have raised the bar for head protection in the genre with the d3.

Riders like Brendan Fairclough, Aaron Gwin, Steve Peat, Brandon Semenuk, and Cam Zink, 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?
