Not optimal for CPAP use or keeping airway open
I waited to write these reviews until I could use each chin strap for a number of weeks each. The single band chin strap was fairly comfortable, but the way it held my chin closed was counterproductive. In CPR training &#34;Head tilt, chin lift&#34; is taught to open up the airway. I purchased these to help keep my mouth shut while using my CPAP machine. The issue is, they both work by pulling the jaw back towards the ears/apex of the head, which does the opposite of ensuring your airway is in the optimal position during sleep. They did have a noticeable neoprene smell when fresh from the package, but a quick rinse in the sink with diluted dish soap solved that issue. Overall, as far as chin straps go they were of average comfort, and a fair value, but they did not work for the purposes I needed them for.
