What size do I need?

Measure around your head, from under your chin to the crown of your head going just in front of your ears (above your forehead), and back to the starting point under your chin.

Median Sizes are:

Small fits where the chin to top of head measurement is around 54cm
Medium fits where the measurement is around 60cm
Large fits where the measurement is around 66cm

Further lesser or larger adjustment is available on each chin strap size. The circumferences shown are the medium size for each chin strap.

Chin straps help to minimize the problems that occur if air leaks from you mouth whilst using nasal CPAP. These include: a dry mouth or the feeling of air bubbling through your lips as you go to sleep. Chin straps can also sometimes help prevent air swallowing (aerophagia) and the discomfort it causes.

Q : Can you please advise washing instructions without damaging stretchiness ?

A : Wash weekly in warm soapy water, rinse and dry but not in direct sunlight. The Seatec will stretch slightly over the first month.


Q : Can we see a diagram how worn?

A : It goes over your head and under your chin.


Q : Does the Chinstrap go on outside of your CPAP mask or on the inside. In other words what goes on your face first?

A : Mask, then chin strap


Q : Will this item help reduce snoring if used by itself?

A : This will reduce minor snoring if the snoring is caused by muscle relaxation. This is not a prescribed therapy for snoring or sleep apnea. If the snoring is consistent it is best to have a chat to your GP.

    Seatec Chinstrap

    Posted by Walter on 3rd May 2019

    The Seatec Sleeptight Chinstrap certainly does the job to stop me mouth breathing while using my CPAP machine. It does however stretch after a few weeks, requiring adjustments, until it needs replacement after only a few months, it is, however the best of the bunch, of the ones that I have tried.

    The key to comfort with the chinstrap is the amount of padding on the part touching the chin. There is a stitched join in the fabric at this point and if the stiches can be felt then the strap can become irritating. More padding there would be an advantage.
