A full-face mask system for delivering a supply of breathable gas at positive pressure to a patient's airways to treat a respiratory disorder, the mask system comprising: a shroud; a cushion module that engages the shroud, the cushion module including a frame and a full-face cushion adapted to engage the patient's face generally along nasal bridge, cheek, and chin regions of the patient's face, the frame at least partly defining a breathing chamber; an elbow connected to the frame in a releasable and rotatable manner, the elbow being adapted to be connected to an air delivery tube to deliver breathable gas to the patient; and headgear directly or indirectly attachable to the shroud in a removable manner, wherein: the frame includes an opening, the elbow including a distal end releasably inserted into the opening of the frame with a snap-fit connection to retain the elbow with the frame, whereby the snap-fit connection between the elbow and the frame also maintains the shroud in engagement with the frame. There are two apertures in the shroud, one for the protruding vent and another for the elbow connection.
