1. A patient interface for sealed delivery of a flow of air at positive pressure with respect to ambient air pressure to an entrance to the airways of a patient including at least the nares of the patient, wherein the patient interface is configured to maintain a therapy pressure in a range of about 4 cmH2O to about 30 cmH2O above ambient air pressure in use, throughout the patient's respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing, said patient interface comprising:
a plenum chamber at least partially forming a breathing chamber pressurisable to a therapeutic pressure above ambient air pressure, said plenum chamber including a plenum chamber inlet sized and structured to receive a flow of air at the therapeutic pressure for breathing by a patient;
a seal-forming structure constructed and arranged to seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal-forming structure having an opening formed therein such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient's nares; and
a vent comprising a plurality of holes constructed and arranged to allow for the washout of exhaled gases,
wherein the plenum chamber comprises a textile outer layer, a textile inner layer and a foam inner layer disposed between the textile outer layer and the textile inner layer, the textile outer layer and the textile inner layer being respectively joined to opposing sides of the foam inner layer.
