The Troy Lee Designs D4 Carbon MIPS epitomizes a commitment to racing performance. Featuring a feather-light carbon fiber shell, the D4 Carbon raises the bar for rider safety with its MIPS (Multi-directional Impact Protection System) liner. The D4 sources wind tunnel-tested aerodynamics, lightweight titanium hardware and efficient high-flow ventilation. The D4 Carbon MIPS doesn't skimp on styling either, with sleek lines, superb fit and finish and attractive colorways. Developed with feedback from TLDs stable of top-level pro riders, like Steve Peat, Brendan Fairclough, Cam Zink, Brandon Semenuk, Sam and Alise Willoughby, no helmet has won more DH World Cups, Redbull Rampage events, or Olympic Medals than the D4. Simply put, the D4 Carbon MIPS brings top-level racing performance to real-world riders.
