NecksGen REV Head Restraints keep you safe while allowing for a full range of head motion and improve driver comfort, unlike other restraint systems. Restraints are available in multiple sizes for an exact fit and are all SFI 38.1 certified. The low profile design and shoulder/collarbone padding not only increase comfort but make getting in and out of the car in emergency situations easier. Winglets for adult sizes accept 2 in. or 3 in. belts and aid in keeping your harness in place even after a multiple impact situation where the belts could loosen. All restraint systems include a quick release and hard mount helmet hardware.
