Which Chin Strap?

Hello,

I use a Quattro FFM as my mouth tends to open while I sleep. I have a opus 360 pillows mask that I really like but keeps opening mouth. I dont like tape but wants to try a chin strap with it. any suggestion on which one?

I would suggest the chinstrap that I use. See below. Or Ruby chinstrap.




But b/c I often sweat on my face at nights I am looking for a chinstrap that is more airy.
May be made of cotton like this, but without the cap:

I use the Ruby Adjustable chin strap. It allows me to lock it on, or let it go a bit loose. I am training my unconscious brain to keep its mouth shut. It's a learning process, I am not there yet!
