The concept works to keep the mouth closed if you are a back sleeper but it is uncomfortable for side sleeping on the velcro side.

Not only is the product good for keeping your mouth closed while sleeping, but it also performs well when meditating. Often, I would meditate and my lower chin drops and I start mouth breathing. I have to break my relation to close it back up. The chin strap, however, allows me to completely relax while also keeping my mouth closed.

Absolutely fixed my problem.

After struggling over a year, FINALLY since using the dual band I have had more sleep full nights but even better yet I have had the fewest events and FINALLY I have more energy and confidence when I wake up.. This was not an easy project but Edwin with his patience and determination was able to give me the confidence and not dreading going to bed any more. This is the SUPER BEST SUPPORT and not only caring about selling a product but going to all means to make sure it works. I thank them every night when I go to bed. I gave them a 5 star only because there wasn’t a 10 star rating to give this chinstrap.

I've tried about 6 different chin straps and they were all too stretchy to keep my jaw closed. I've been looking for for one that is not made from elastic material like neoprene. This chin strap comes with a comfortable non-elastic strap that pulls up instead of inward like some. It also comes with a second elastic strap to make it even tighter. Make sure you measure your head and get the size that best fits you. The cap is very comfortable but it does hold in more heat so you might need less blankets.

This chin strap actually works. It lifts the chin up instead of back. Stays in position. Really great quality. Worth every penny.

This is an excellent product that v performs as promised.

The Knightsbridge Dual Premium chinstrap is the 4th chinstrap I have tried during the last year and by far the best. I had a problem not only with open mouth breathing but also with air leakage from my CPAP machine. Both problems seem to be solved. It does exactly what is advertised--it lifts your jaw upward instead of pulling it toward the back of your throat. It's by far the most comfortable chinstrap I used.

I use a cpap machine and I always had tge problem of my jaw dropping. I would wake up during the night with a dry mouth. I tried mouth taping, but would not help because my jaw would still drop and the air would escape. This chinstrap solved all those problems. Now I can't sleep without it.

Probably the best head strap that pulls up, for open mouth problem. I use earplugs for Audible listening and the holes are a necessity. Slight problems with velcro hanging up on Cpap mask strap, but I can live with it.

This is my second Knightsbridge headgear and I love it even more than my first. I love that they are always improving their products. It fits so comfortably that I forget I have it on. Great product!

Works well good quality 

Does as advertised doesn't cause TMJ.

Great chin strap. Has transformed my sleep and completely stops my snoring. Only thing I wish it had in the XL was more Velcro for the strap behind the head so it can be tightened more. But overall amazing design.

It's great. Just what I was looking for. Fits comfortably and stops the open dry mouth as well as snoring.
