The adjustable Velcro cross strap should be set to the width of your neck - this prevents side movement of belts - especially if belts are not secured directly behind the driver to the roll cage mounting bar. !/2? thick XHD fire resistant foam is used for maximum comfort. Quick Velcro installation or removal. (Cross web fits just behind drivers neck and may help driver being ejected from belts in an incident)
Lumbar Support aids in the reduction of fatigue and lower back pain. Fully adjusts to your personal comfort! Designed for use when the driver’s seat does not provide adequate lower back support, or when already existing lower back pain is present. Lumbar Support can only be incorporated with pull-up adjusting lap belts
