Fitting Instruction

  1. Open up the chinstrap, so it is flat, and make sure the thin strap points towards the top of the head. The wider strap will be on the bottom.
  2. Pull the chin cup over the chin
  3. Close the top strap with the Velcro, adjust as needed
  4. Close the wide back strap (this is sitting on the back of your neck), adjust velcro as needed
  5. Your ears will sit in the ear cutouts

The design of this chinstrap may inadvertently push your jaw back as you tighten the velcro on the back of the neck. This may exacerbate your sleep apnea. If this occurs, we recommend trying a dual-band design chin strap such as the Knightsbridge chin strap.

I love it , it works much better than others that I have bought

The Ruby chin straps used to be excellent; they were soft, comfortable, and easily adjustable for a perfect fit. I don't know what happened to the quality, but the last one I ordered was not adjustable and way too small. I tried to cut this one and use the velcro extension piece I had from a previous Ruby chin strap that wore out but velcro does not adhere to this new one. I am very disappointed in the newest Ruby chin strap. Perhaps there is a different manufacturer? I don't know what happened to the quality, but I would like to get the old Ruby chin straps back.

Judy, I am so sorry to hear that! Please contact us so we can help rectify the issue for you.

I ordered a medium and thought it was too small. However, after several nights it has straight enough to no longer cause pain. First night I had to take it off about 4 hrs in. The night before last I went 9 hrs without irritation. Now my nose mask has to be loosened as it is now too tight. It keeps my mouth shut all night. I now have lots of water left in my Resperonics machine.

Purchased several for future use based on prior experience with this product. I find fixed size chin strap to perform better than adjustable style. Look forward to continued successful performance with these items.

The medium was too small so exchanged for a large also way too small. The item seemed well made but made my head feel like it was in a vice. Too uncomfortable to keep so sent the large back also.

Not Adjustable!!
One piece. Keeps my mouth shut. Too tight. Jaw pain. Feels like switch and bait.

The Ruby chin strap has two models. One is adjustable and one is not. You can get the adjustable in X-large.

I just bought the fixed ruby chin strap after having used the adjustable version for years. Based on the head measurements listed, I thought the large fixed might fit better than the adjustable version. I was so wrong. It fit like a tourniquet and I could barely pull it on let alone wear it. What a total waste of money.

Hi Judy, I am very sorry you are unhappy with this design. Please reach out to us and we can help provide a better option or a different size.

Great chin strap. This is my second one. Since it’s adjustable, I always get the perfect fit. Hope Cpapman stays in business a long time so I can keep on ordering from them.
