Tried and tested, the Mirage FX is one of the most popular nasal masks. In to our experience, the mask is suited to 90% of all users and shines out through an excellent price-performance ratio. Particularly suitable if you breathe through your nose while sleeping, suffer from claustrophobia or if a clear field of vision is important to you. Two sets of Velcro fasteners to ensure easy adjustment of the headband. The forehead piece is wing shaped - by tightening the headgear at the top it flattens the forehead piece out and pulls the mask cushion closer to itself. At the same time the flattened forehead piece, distributes the pressure in a pleasant fashion. The double-walled mask cushion also ensures the pressure is evenly distributed. The hose / tube can be removed from the mask with a simple click. The mask is very quiet and easy to clean. The headgear has a arched cut-out at the base of the neck to reduce pressure in the neck area and thus avoids tension-related headaches.
