With its running supremacy in the full face helmet market, the D4 range has just increased its lead over the competition with its new Polyacrylite model. Featuring safety and comfort equal to the more premium carbon and composite helmets, the Poly delivers it in a more affordable package. That being said, Troy Lee Designs has packed in features such as MIPS® C2 brain protection, air intake systems to keep your head cool, and a singularly premium anatomical fit, making the D4 range one of the most sought after full face helmets in the mountain biking scene.
