First post- Leaking from mouth, using chin strap

[Rgn3]

I use nasal pillows and even with a very good Chinese made chin strap and a collar I still get a mouth leak, or should I say a leak through the lips.

Discouraging. My chin strap stretches so I have to frequently adjust it. What brand of chin strap are you using?

P.S.  to everyone: The "quote multiple posts" button does not work for me. Not sure why.

I find my ResMed chin strap almost useless, mainly because it's not very secure.  If it had more than one strap going around your head, it might be better.  

But as the others have said, chin straps in general haven't stopped my mouth leak ... air slips through my lips easily, even with the strap tightened to almost vise-like tightness.  What the chin strap IS good for (when it stays on my heads, that is) is stopping my jaw from going slack when wearing a full face mask.  I'm currently using (and not have a lot of success with) a Respironics Amara View full face mask. I found that when my jaw relaxed and my chin dropped, I was getting a ton of leakage around my chin.  The chin strap helps to stop that from happening.
