The M4 Pro Xtra is a multi-purpose, lightweight helmet designed for drivers who prefer the full range of vision of an extra large eyeport. The M4 Pro Xtra is a fully ventilated helmet featuring aggressive chin bar vents with a shell that is 5% larger than a standard extra large helmet.
In addition, the M4 Pro and the M4 Pro Xtra feature our new SRV friction shield system*. This new system has a slide mechanism that allows the driver to adjust the tension on the shield allowing for multiple opening positions. When properly adjusted and in the locked position, the SRV system helps reduce the possibility of the shield opening during an impact.
