In a Nutshell
Designed to support the jaw in a forward position during sleep, Sleepeeze Chin Strap may help prevent snoring
Airway Assist is designed to support the jaw in a forward position during sleep keeping the mouth closed and airways open,  allowing air to easily pass through. This prevents air traveling to and from the throat and over the tongue, potentially minimizing rapid flapping that can be the cause of snoring.
