The Ruby Adjustable Chinstrap is an updated design from the original Tiara Topaz Adjustable Chinstrap. Cardinal Health has upgraded this product with Breathe-o-Prene material and an improved Velcro attachments.

The design of the adjustable chinstrap can push your jaw backwards, which may inadvertently increase the severity of your sleep apnea. It does take about a week to get used to. Making sure you’re putting it on correctly is also a key factor. It’s pretty easy to put it on wrong and it feels totally too tight and wrong when you do.

The adjustment is a little tricky and you can easily wear it inside out without realizing it. Adjustment has to be done in a strict sequential manner. First you disconnect both velcro strips. Then put it around your chin and adjust the strap at the top of your head fairly tight, but not too tight. Then you connect the strap at the base of your skull above your neck.
