A patient interface comprising a nasal seal 103 including a face contacting side, formed of a soft flexible material, and including a central portion to extend across the base of the nose, and a side portion extending from each end of the central portion. Each side portion extends across a side of the nose. A face contacting side of the seal is supple to conform under internal pressure to the surfaces of the nose of a wearer, including, at the side portions of the seal, to outside surfaces of the sides of the nose. An exterior side includes regions much stiffer than the supple interior side, the regions extending into the side portions of the seal. Straps 105, 115 to hold the interface in place may be provided. |
