Traditional chin straps vs. Dual Band chin strap

Traditional chin straps

Traditional chin straps come in two varieties, linear and split. Both work on the same principle. They are made of a single elastic material (usually neoprene) and wrap around the tip of the chin. Notice the straps wraps around the tip of the chin and the force is directed towards the ear, and the jaw joint is located just in front of the ear. So almost all the force applied by a traditional chin strap is directed into the jaw joint.


Traditional chin straps are intended to immobilize the jaw by increased friction in the jaw joint. This is problematic since sufficient force can be painful and long-term use can cause damage to the joint. What is needed is an upwards force, but almost none of the force applied by traditional chin straps is useful in rotating the jaw upwards.


Breathable Three-Layer Open-Net Mesh

The Premium cap is a three layer net-mesh and the cap of the Plus version is made of 100% Indian manta cotton. This provides breathability while still being strong and durable. 


The Dual Band chin strap uses 6 materials plus Velcro and is an assembly of 24 different pieces. All six materials and the full cap design are necessary to provide the vertical lift and compound elastic-non elastic pressure functionalities and also be comfortable. The elastic and non-elastic straps produce a compound force curve that allows the pressure to be minimized. For the cap to be durable yet also light and breathable, it has the three-layer net-mesh construction. Since a full cap is required to balance the vertical forces at the front, and because it needs to fit heads of various sizes and shapes, the cap is constructed of three panels and has a rear size-adjustment strap. Because the cap and a portion of the Velcro (which is a somewhat stiff material) covers the ears, there is an interior soft grey felt lining to make that comfortable. And to provide comfort for wear over months or years, the entire perimeter of the cap is also lined.


Dual Bands

The Dual Band chin strap by Knightsbridge Sleep Solutions has a revolutionary dual-band design. The non-elastic blue strap prevents the jaw from lowering. The elastic (black or white) strap provides a gentle upwards force .


This graph shows why the compound elastic - non elastic force is comfortable . The force produced by the steep vertical dashed line keeps your jaw elevated in the comfortable, low-force yellow zone.



Vertical Lift


The bands pass under the jaw and attach to the velcro patch near the temples, thereby providing a vertical force.



Vertical force works with the natural rotation of the jaw.



Revolutionary Design

 Either of these features alone ( dual bands or vertical lift) would produce a chin strap superior to any other. The combination of these two innovations provides far and away the most effective and comfortable chin strap on the market 2024. That's why the DUAL BAND has been widely acknowledged as the ''BEST CPAP CHIN STRAP".


Finally, the chin strap problem has been solved. If you need a chin strap, this is the chin strap you need.
