My old Chin strap was not longer staying closed so i looked for something better. I saw this product and while it looks huge compared to the old one i was pleasantly surprised how the size had no impact on my sleep. In fact i found it comfortable. I have a beard and it was not itchy at all. My Dreamwear fit over this nicely and did not interfere with it staying under my nose. You can even tighten it on the top as well if you feel your mouth is not staying as closed as you like. I got it because at times my mouth will open and the air escaping can wake up my wife.
