The REV X Carbon is NecksGen's newest head and neck restraint / frontal head restraint. Hand made from carbon fiber and lightweight materials, the new REV X adds an extra element to driver comfort. The X strap system holds the device securely in place while driving, and also helps keep it where you want it while getting in or out of the vehicle. The straps are easily adjustable to make personal fitment easy, and the double adjustable tactical buckle in front is easy to use. The vertical chest straps have some adjustment to fit men and women both easily.  
Quick release helmet hardware is included!
Currently available with accommodations for 3" wide belt guides that work with 3" or 2" wide shoulder belts.
"Does it work with a 3 point harness?"
The REV X Carbon has been shown to reduce neck loads under impacts when tested to the NHTSA FMVSS208 standards using a 3 point belt. We always recommend you race with at least a 5 point harness for safety, but we understand that in some circumstances a 3 point is all that is available, and the REV X Carbon will add an extra layer of protection.
