The Knightsbridge has an award-winning revolutionary dual band + vertical lift design. The bands pass under the jaw to lift vertically, working with the natural rotation of the jaw. The non-elastic blue band prevents the jaw from lowering, and the elastic (white or black) band provides a gentle upwards force. These two innovations allow force to be minimized for maximum comfort, yet still effective.

I really like this cap, it does the job and it's not uncomfortable. Would give it 5 stars if it came with the lining on both ears.
I liked how it fit and everything worked as advertised, for the first month, then the fuzzy velcro side is getting really worn out. I have had other items that use velcro that have lasted years so this must be made of cheaper materials. Other than that I think the head strap works great.
