The REV2 Carbon is new for 2020, and is currently the lightest head and neck restraint available. The Medium 2″ tips the scales at less than 1 pound! The simple, small, easy to use design carries over from the popular REV2 Lite, and has the same level of certification and safety as all NecksGen head and neck restraints. The adjustable tether makes setting your slack and range of motion quick and simple. No need to worry about your seat angles or fiddly straps around your chest. Just put your belts on and go. Available in sizes to fit most all drivers from teens and up. Quick release helmet hardware is always included with all NecksGen head and neck restraints, and be sure to choose the “free shipping” option at checkout!
