Active sleepers need an active mask and ResMed's new Mirage Activa's is the only mask in the world to feature ResMed's ActiveCell Technology to create an active, adaptable seal. ActiveCell Technology creates a dynamic defense against the problems created by active sleep.

The Mirage Activa's cushioned chamber is air filled and sealed with an "independent suspension" system that expands and contracts to adapt automatically and compensate immediately to the movements and shifting that occurs during active sleep.
