just got to keep my mouth shut!!

Just curious. Those who use chin straps, do you put them on before you put your mask on?

There is no right or wrong way. My way put mask first and than chinstrap. Being active sleeper, the chinstrap helps keep mask in place

Do you mind if I ask how long it takes for it to stretch out to the point that it is not useful? Are you talking about the Ruby or a different one?

I use the ResMed Sullivan chin strap. It takes a couple months, I guess, before I have tighten it up a bit. After about a year or so it has stretched so far I have to toss it and get a new one.

I know it needs to be tightened up when I start mouth leaking. That is, I'll notice when I wake up with air hissing out of my mouth, my machine reports a percent time in large leak greater than 0%, and a check of my data with SleepyHead and Encore reveals that indeed I've spent a significant amount of time in large leak.

I put my chin strap on first. Then the mask straps go over top of it helping to keep the chin strap in place.

Others will put their mask on first and then the chin strap over top helping to keep the mask in place.

It all depends on the designs of your chin strap and mask, and your personal preference. Just keep in mind that you will probably have to adjust your mask straps a bit looser if you put it over your chin strap.
