This deluxe full face CPAP mask provides effective sleep therapy with one big difference—it's comfortable enough to actually sleep in! Its soft silicone design conforms comfortably to your face, while frame stabilizers redistribute pressure evenly over a large surface area, increasing the mask's effectiveness and reducing risk of leaks. And unlike others, this CPAP mask is designed with NO clunky forehead pad, so you can read or watch TV before drifting off without anything blocking your movement or view, then sleep comfortably through the night. Even the headgear is designed for your comfort, in a special breathe-o-prene fabric which resists moisture. The full face CPAP headgear fits securely, feels like a dream and works effectively, helping maximize sleep apnea therapy all night ... every night. Specify size, measuring from bridge of nose to bottom of lower lip: (small; 3"-3 1/2"), (medium; 3 1/2-4") or (large; 4"-4 1/2"). Latex-free plastic.
