1. A patient interface structured to receive a flow of pressurised air for breathing by a patient, the patient interface comprising:
a plenum chamber pressurisable to a therapeutic pressure of at least 4 cmH2O above ambient air pressure;
a seal-forming structure constructed and arranged to seal with a region of a patient's face surrounding an entrance to a patient's airways, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout a patient's respiratory cycle in use;
a positioning and stabilising structure configured to hold the seal-forming structure in a therapeutically effective position on a patient's head; and
a stiffener coupled to the plenum chamber, the seal-forming structure, and/or the positioning and stabilizing structure,
wherein the patient interface is configured to leave a patient's mouth uncovered, or if the seal-forming structure is configured to seal around a patient's nose and mouth, the patient interface is configured to allow the patient to breathe from ambient in an absence of the flow of pressurised air,
wherein the seal-forming structure and/or the positioning and stabilizing structure is constructed from a first textile material, and
wherein the stiffener is constructed from a second textile material configured, upon application of a treatment, to have a treatment-induced stiffness that is greater than a stiffness of the first textile material.
