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 for a clip.
