A nasal mask assembly for nasal CPAP therapy, comprising: a mask frame; a silicone nasal seal which can be repeatedly detached from and reattached to the frame; an elbow rotatably coupled to the frame and adapted to connect to a gas delivery tube; and a headgear assembly to secure the frame and nasal seal to a patient's head. The headgear assembly includes a pair of relatively flexible, Y-shaped straps (84) having a relatively soft fabric and foam material construction, and a stiffening layer (92) made of a relatively rigid material compared to the strap material. The stiffening layer is attached to an outside surface of the pair of straps resting against the cheek regions in use. The stiffening layer is narrower than the strap portion. |
