Dual-Wall Cushion with Spring Air Technology: The Mirage Quattro's dual-wall cushion with spring air technology follows the contours of your face and gently adjusts the seal accordingly. The moving cushion membrane and nasal bridge accommodates different types of nasal structures and prevents leak into the eyes.

Breathe-O-Prene Headgear: The Mirage Quattro comes with ResMed's Adjustable Breathe-O-Prene Headgear. Breathe-O-Prene fabric actually whisks moisture away from the face rather than collecting it so that the material stays dry and comfortable during use.

Ultra Quiet: The Mirage Quattro has built-in vents which disperse air gently and quietly so you and your partner can enjoy a good night's sleep. This improved vent design reduces noise by over 50%. The Mirage Quattro's range of set-and-forget options mean that the mask can be precisely adjusted (even while its being worn) to create a perfect fit that stays perfect every time you take off the mask and put it back on.

One Handed Adjustment: There’s no need to take off your mask to use the MicroFit dial. You can simply adjust the dial with one hand while wearing the mask, and even while lying down!
