THE REIGNING CROWN OF FULL-FACE HELMETS

D4 reigns king atop downhill podiums and freeride events across the globe. Available in carbon and composite, details are what makes the D4 the most coveted full-face in mountain biking. Prioritizing safety while balancing weight through premium construction and materials, D4 incorporates MIPS protection with an EPP chin bar and anatomical cheek pads with emergency release.

This helmet is designed and intended exclusively for use by bicycling activities, including mountain biking and off-road cycling.

    Features

    MIPS
    MIPS Brain Protection System designed to reduce rotational motion transferred to the brain from angled impacts to the head.

    Shell
    Built with an aerospace shell design and materials, we were able to get the D4 Composite helmet to 1050 grams without sacrificing any strength.

    Cheekpads
    Anatomical "3D” contoured cheek pads with emergency release system for EMS responders

    Liner
    Removable snap-in, washable comfort liner with Coolmax® and Dri-lex® moisture-wicking materials

    EPP
    EPP (Expanded PolyPropylene) chin bar

    Ventilation
    For comfort, the D4 Comp routes cooling air through a front air intake system that flows through the polymer center and power grid side mesh keeping your head cooler during the ride.

    How to Fit

    With a fabric tape measure around the circumference of your head holding the tape just above your eyebrows and ears. 1” = 25mm
