Nacksgen REV Head and Neck Restraint
Note: Small device is only compatible with 2" shoulder harness. Medium size can be purchased for either 2" or 3" harnesses (see options).
Sizing the REV is simple when using this chart. Fitment is based on personal preference, and sizing isn’t necessarily limited to the measurements shown. If your neck is wider than the inside diameter of the device shown, the device will function properly, but some comfort will be sacrificed. If you are on the edge between a medium and a large but have narrow shoulders, go with the medium.
