The Halo Chinstrap by Sunset Healthcare Solutions is a mask accessory used as a chin support during sleep. When the mouth is left open, airflow may leak, causing therapy to be compromised. It may also cause nasal and oral dryness, making the patient uncomfortable upon waking.
This chin strap feels light weight which isn't necessarily a bad thing. I don't know how well it will hold up. It may be made very well, but I'll wait and see. My only complaint at this time is that it is not very comfortable. It rests right on the edge of my ears to be able to stay on my chin. I would prefer it to cup the chin because it feels like it will just slide off while you sleep.
