A patient interface assembly includes a flexible cushion configured to sealingly engage the patient's nares and a frame with a pair of flexible extending members that extend laterally from opposite sides of the frame. The frame and the flexible cushion together form a chamber. The patient interface assembly also includes a positioning and stabilising structure configured to maintain the flexible cushion in engagement with the patient's nares. The positioning and stabilizing structure has a pair of headgear straps. Each headgear strap is connected to a respective one of the flexible extending members. The flexible extending members do not form an airflow path for the breathable gas. The headgear straps have a multi-layered structure, at least one layer being made of fabric and at least one layer being made of plastic. In addition, the at least one plastic layer is a rigidizer that adds rigidity to the respective headgear strap.
