Improving upon the class-leading D3 helmet was no simple task, but Troy Lee Designs is never one to rest on its laurels. Built with an aerospace-grade composite shell, the new D4 Composite helmet weighs in at just 1050-grams without sacrificing any of the strength of the previous model. MIPS C2 protection system is used to mitigate rotational impacts, while the front air intake system with 24 vents keeps your head cooler than ever during intense rides. Washable X-static and XT2 anti-odor padding keep the inside of the helmet feeling fresh, and there's now an EPP collarbone impact system that helps reduce the forces transferred to this sensitive area.

Would not wear any other brand helmet. Fit is perfect. Very light, fast shipping. Would be nice to receive an extra visor with the purchase like I did with my MX helmet.

I was looking for something that provides more protection than my TLD Stage helmet that I love. I wanted this to wear at the bike park. It’s an awesome helmet. I went with a medium as I was in the middle to the top of the medium measurements. The medium is snug but not uncomfortable. If your head measures to the top of the medium size chart and you don’t like a snug / tight fit then maybe a large however I know the pads will stretch/ break in. Obviously you want it snug so it works properly. It feels like a super light weight motorcross helmet. It has typical TLD fit and finish which is top of the line.
