A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways comprising: a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure; a frame member attachable to the retaining structure; and a positioning and stabilising structure attachable to the frame member.

A method for producing an annular hair band includes providing an elongated, elastic woven strip having transversely extending yarns interleaved between longitudinally extending yarns. Two ends of the woven strip are overlapped. An abutting area of the two ends is greater than a cross sectional area of an end face of each end. Two non-planar dies are used to heat and compress overlapped sections of the two ends. The yarns of one of the two ends and mesh holes of another of the two ends are fused together. The two ends are flattened to form protrusions or grooves on an upper face and a lower face of a non-planar engaged portion of the two ends, thereby forming the annular hair band. The two non-planar dies are opened to remove the annular hair band for cooling. The annular hair band is capable of withstanding a stretching force greater than 2 kg.
