Said plurality of straps comprises at least one upper strap configured to extend above the patient's ear, at least one lower strap configured to extend below the patient's ear, and at least one top strap configured to extend over a top of the patient's head. At least a portion of said plurality of straps includes a first layer of fabric and a second layer of fabric, said first layer being constructed and arranged to be located on a patient-contacting side in use, and said second layer being constructed and arranged to be located on a non-patient-contacting side in use. The first layer and the second layer are joined at a joint positioned away from the patient's face when in use. The headgear has a first region having a first extensibility and a second region having a second extensibility, the second extensibility being different than the first extensibility.本発明はヘッドギアと、マスクを患者の顔における所定位置に保持するために用いられるヘッドギア製造の方法に関し、このマスクは例えば持続的気道陽圧法（ＣＰＡＰ：Ｃｏｎｔｉｎｕｏｕｓ Ｐｏｓｉｔｉｖｅ Ａｉｒｗａｙ Ｐｒｅｓｓｕｒｅ）、又は非侵襲的陽圧換気（ＮＩＰＰＶ：Ｎｏｎ－Ｉｎｖａｓｉｖｅ Ｐｏｓｉｔｉｖｅ Ｐｒｅｓｓｕｒｅ Ｖｅｎｔｉｌａｔｉｏｎ）を用いた睡眠呼吸障害（ＳＤＢ：Ｓｌｅｅｐ Ｄｉｓｏｒｄｅｒｅｄ Ｂｒｅａｔｈｉｎｇ）の治療のために用いられる。
