* DUAL BANDS: Non-elastic blue band prevents jaw from lowering. Elastic white band provides gentle upwards force. Compound elastic-nonelastic force allows pressure to be minimized while still effective.
* VERTICAL LIFT: Bands lift from under jaw and attach at the temples to produce vertical force. (Unlike standard neoprene chin straps which wrap around the tip of the chin and push the jaw directly into the jaw joint.) 
Vertical lift works with the natural rotation of the jaw.
* COMFORTABLE: Washable. Light, breathable net-mesh cap.
