    a seal portion that extends from the flexible body to a free hanging end of the seal portion, the seal portion being shaped to seal with a face of the patient around nares of the patient when the mask is worn by the patient, the seal portion defining a first aperture to provide air from an interior of the mask to the airways of the patient, the seal portion surrounding the first aperture and being shaped to contact a tip of a nose of the patient when the mask is worn by the patient, the free hanging end of the seal portion surrounding the first aperture;

    a first thickened support portion that extends from the flexible body on a first side of the mask to a free hanging end of the first thickened support portion, the free hanging end of the first thickened support portion being separated from the free hanging end of the seal portion by an air gap, the first thickened support portion mechanically supporting the seal portion at the first side of the mask when the mask is worn by the patient; and

    a second thickened support portion that extends from the flexible body on a second side of the mask opposite from the first side of the mask to a free hanging end of the second thickened support portion, the free hanging end of the second thickened support portion being separated from the free hanging end of the seal portion by an air gap, the second thickened support portion mechanically supporting the seal portion at the second side of the mask when the mask is worn by the patient; and

    headgear structured to maintain the mask in position on the face of the patient when the mask is worn by the patient, the headgear including;

    a first side headgear portion attachable to the mask at the first side of the mask so that the first side headgear portion extends between a first eye of the patient and a first ear of the patient on a first side of a head of the patient when the mask is worn by the patient; and
