Details make the D4 the most coveted full-face in mountain biking, including Mips C2 brain protection, an air intake system for ventilation, and an unmatched anatomical fit.

• Mips C2 system and advanced Polyacrylite shell for rotational impact protection
• Front air intake with high-flow polymer center and power grid mesh for ventilation
• Collarbone Suspension System and breakaway visor screws for added safety
• Anti-microbial padding and quick-release 3D cheek pads for optimized anatomical fit
