The peak of this helmet is 14mm longer and 5mm wider than the VX-PRO3. Larger relief ports allow more air to escape from under the larger peak to minimize lift/pulling at speed. The chin vent incorporates expanded SS mesh that is moved from the inside to the outside of the shell, providing room to move the EPS chin liner forward to allow more room in the face area. The chin vent has a round and smooth mesh cap to resist snagging and digging and is easily removable with a single screw, that will breakaway, if necessary, in an impact. The Inner Mud Gate can be easily removed for more airflow.. . The liner components feature FCS cheek pads that have a larger surface area, wrapping under the jaw for more comfort. A removable, replaceable, washable neck roll pad, and 5mm peel away cheek pads and temple pads.
