The SnugFit Style Chinstrap from AG Industries is a simple, adjustable chinstrap without the added straps or bells-and-whistles of some other straps. It comes in a rich black fabric and includes a simple Velcro mechanism at the top of the head for adjusting it to the best size for you. The SnugFit Style is a great option if you notice you're losing air though your mouth or find your mouth feels quite dry when waking up after CPAP or BiPAP therapy.
