1) what kind of chinstrap do you use?
Hi Sheriff,
Actually, I used two different ones.
The first was a CareForce Medical. I used the Velcrow to size it properly, had my wife stitch it and then taped it to the mask, because I was afraid it might come off the mask. Then it dawned on me that with it being stitched, if the elastic stretched, I would have a problem with its tension. So, I decided to just try wrapping it around the mask and my head and attaching the Velcrow. It worked perfectly. For 10 nights it hasn't come off once.
It allows me to use the headgear (particularly the top straps) with a very loose fit. The chinstrap, which is snug, but not all tight, seems to really stabilize the mask. As I wrote in another post, I am able to use it with my Termpru-pedic pillow with no problem. Since the top is positioned well and stabilized, as needed I can adjust the bottom straps if I have any leaks there. The net result is the mask is substantially looser and the leaks are virtually eliminated. (AND gone are the nose bridge problems, air in the eyes, pressure grooves, etc., etc.)
I think any elastic strap that had a good Velcrow connection would work. I only tried the chinstraps because I had them.
Below I have attached pictures of the strap on the mask.
