FlexSet Chin Strap with Velcro

Easy Fitting Chin Strap

The FlexSet Chin Strap by DeVilbiss is a high quality, skillfully engineered piece of equipment designed to stabilize your mask and prevent mouth breathing during therapy. The FlexSet chin strap is very easy to fit - simply place your chin inside the cradle and then wrap the opposite end around the top of your head; then, adjust the Velcro straps to suit your specific head size. The FlexSet chin strap is composed of a soft material and will adapt to accommodate your particular facial structure; it will also accommodate movement so you can shift around during sleep and maintain a stable fit.

Correction of Mouth Breathing

Along with extra stability, this chin strap confers another benefit: correction of mouth breathing. When properly fitted, the FlexSet chin strap will prevent your mouth from dropping open during sleep. Thus, with this chin strap you'll be able to eliminate the consequences associated with mouth breathing during therapy, such as dry mouth and lesser quality therapy.
