The bands of the Knightsbridge Sleep Solutions chin strap lift *vertically* from under the jaw to work with the natural rotation of the jaw. (In contrast, traditional chin straps wrap around the tip of the chin and force the jaw backwards and into the jaw joint, which is uncomfortable and long term use can cause joint damage.) And just as importantly, this chin strap has two bands ... an elastic band and a non-elastic band. The non-elastic band prevents the jaw from lowering, and the elastic band provides a gentle upwards force. The compound elastic-nonelastic force allows the pressure to be minimized yet still effective.
Either of these two innovations alone (dual bands or vertical lift) would make this a superior chin strap. The patent-pending combination of these innovations makes this far and away the most effective and comfortable chin strap available.
