Stronger, rounder and smoother shell compared to the previous generation. The smooth, round shell design allows the helmet to "glance off" impact energy, helping to prevent that energy from transferring to your head and body before the EPS foam is tasked with absorbing that energy. Constructed with a uniformly strong vacuum formed Super Fiber, 30% Stronger than traditional fiberglass. DOT Approved, Meets FMVSS 218 Standards. Widened, more open interior / jaw area for added comfort and easier ingress. VAS-A face shield system allows for tool-less change and removal. Designed to be easily removed for use with goggles. Most goggles can clear the shield in the raised position without removal. Pinlock ready (Pinlock 120 Lens Included). Redesigned to prevent wind buffeting at highway speeds. Easily removeable (1 flat-head screw per side) for improved high-speed stability. Adjustable height to fit rider preference. Forehead logo vent ducting allows for optimal airflow in any riding position. Top vent for improved top-of-the-head cooling in hotter climates or conditions. Chin vent with large intake ports, double the size of the XD-4 chin vents. Inner chin vent shutter for additional tunability of the chin vent's airflow and direction. Rear AR Spoiler draws hot air out of helmet, while reducing turbulence at high speeds. Chin, forehead, top and rear spoiler vents are adjustable to your preference or riding style. Fully removable/replaceable/washable comfort head liner and cheek pads. Constructed of odor resistant materials. Removable 5mm foam on left and right for micro fitting, along with adjustable top liner. Pull-down air flap under the chin bar reduces wind intrusion and improves ventilation. Re-sculpted Hyper-Ridge shell design provides a flat surface for communication system mounting. Seamless speaker mounting without removing the cheek pad covers. Integrated hook and loop panel with a large, deep recess for premium speakers
