A nasal interface for delivering pressurized breathable gas to a user, comprising: a rigid support frame; a removable one piece silicone nozzle structure including a common base portion and a pair of nozzles extending from the base portion; a yoke (580) to provide a degree of stiffness to each side strap, each yoke including a ring shaped coupling (581) connected to the frame to allow localized, rotatable and unified adjustment of the nozzle structure, to align the nozzles with respect to the user’s nasal passages; and a headgear adapted to support the support frame and nozzle structure on the user’s face. The headgear includes a back strap adapted to pass around the rear portion of the user’s head, a top strap adapted to pass over the top of the user’s head, and a pair of depending side straps each of which is suspended from a junction between the back and top straps, the depending side straps being configured to extend forwardly of the ear along the user’s face. |
