The Daytona series of helmets have always set the standard for technology, safety, and artistic design, and the all-new D4 Carbon ups the game even further. Using TeXtreme Spread Tow carbon fiber reinforcements in the shell, the new D4 Carbon has dropped almost 50 grams without sacrificing any of the strength of the previous model. Despite the trimmed down weight, Troy Lee was able to beef up the helmet's protection system by adding EPS impact foam in strategic areas to increase strength and durability. Integrated MIPS helps to reduce rotational motion transferred to the brain from angled impacts to the head, and there's now an EPP collarbone protection system to reduce the forces transferred to this sensitive area in the event of a crash. The new D4 is rounded out with lightweight titanium D-ring adjustments, and quick release XT2 3D cheek pads and X-Static washable liner.
