SleepWeaver Élan incorporates a soft-cloth technology that quietly inflates like a balloon to create an airtight seal. The breathable, non-allergenic mask is comfortable—and it eliminates leaks, pressure points, sore spots, and pinching. Our “loose fit” prevents strap marks, and the open-face headgear design accommodates eyeglasses and allows virtually unrestricted vision—great for people who like to fall asleep while reading or watching TV. The mask features exhalation holes underneath to match up with your natural nasal exhalation. The mask is angled so the exhalation doesn’t bother you or your bed partner.
