Two-Layer Cushion. The mask features Mirage's dual layer cushion technology that uses two layers to achieve a comfortable, secure seal. The cushion is designed with an inner layer for support and stability. The outer layer is a softer silicone membrane that reduces mask leaks and helps prevent pressure sores. Once in use, the mask inflates and forms a seal with no need for over tightening the headgear. The cushion attaches to the frame without the need of a clip.
Easily Adjustable Headgear. The Mirage Vista comes with a Fit Angle Selector that helps the user to select from five symmetrical headgear angles and twenty asymmetrical positions for greater mask stability.
Headgear Quick Clips. Once the headgear is set, the quick-release headgear clips make mask removal simple and prevents the user from needing to re-fit or re-adjust the headgear.
Compact Design. Without a forehead support, this mask allows unlimited patient visibility for reading or watching television before going to sleep.
