The D4 Polyacrylite Mips MTB Helmet delivers professional-grade protection without the premium price tag. Built with advanced Polyacrylite shell construction, it incorporates Mips® C2 rotational impact brain protection—the same technology found in higher-end models. The front air intake system with high-flow polymer center and power grid side mesh keeps you cool during aggressive descents, while the Collarbone Suspension System and quick-release 3D cheek pads ensure anatomically optimized comfort. Breakaway visor screws and anti-microbial padding complete a helmet engineered for serious mountain bikers who demand safety and performance.
