I (Professional Santa) experience dry mouth when using a full-face mask. I have been told this is because of mask leak through my beard. I have been advised to use nasal cushions instead of the full-face mask. When using nasal cushions, I get a serious dry mouth.
It has been suggested that I use a chin strap to keep my mouth closed while sleeping which is expected to eliminate or, at least, reduce the dry mouth. How do I choose the chin strap best for me?
