In use with a patient having long hair, the back strap is adapted to extend under the patient's hair and urge upwardly on the patient's hair and against the patient's head beneath the occiput. In use with a patient having short hair, the back strap is adapted to urge against the patient's head beneath the occiput. In an embodiment, front strap portions of the headgear may be provided with a sleeve or cover (e.g., constructed of a fleece material) to enhance comfort in use. ## Claims ### Claim 1 A respiratory mask for delivering breathable gas to a patient for treatment of sleep disordered breathing, the respiratory mask comprising: an airway interfacing portion constructed and arranged to engage a patient's face for delivery of the breathable gas to a patient's nose and/or mouth; a positioning and stabilising structure constructed and arranged to provide a force to hold the airway interfacing portion in an interfacing location on the patient's face, the positioning and stabilising structure comprising a pair of rigidizers, each of the pair of rigidizers having a front end portion adjacent the airway interfacing portion, the front end portion including a first end structured to connect to the airway interfacing portion and a second end, the first end extending anteriorly of the second end such that the first end is spaced and separated from the second end; and a cover provided to each of the pair of rigidizers and structured to at least partially encapsulate a respective one of the pair of rigidizers, the cover including a slot arranged to allow the first end of the front end portion of the respective one of the pair of rigidizers to extend therethrough towards the airway interfacing portion, and the cover further including a pocket to receive the second end of the front end portion of the respective one of the pair of rigidizers, wherein the cover includes a face contacting side arranged on one side of the respective one of the pair of rigidizers and a non-face contacting side arranged on an opposite side of the respective one of the pair of rigidizers, the face contacting side having a face contacting surface adapted to contact the patient's face and the non-face contacting side having an outwardly facing surface adapted to face away from the patient's face, wherein each of the face contacting side and the non-face contacting side comprises lateral edges, and wherein each of the lateral edges of the face contacting side is directly and fixedly attached to a respective one of the lateral edges of the non-face contacting side to provide a direct and fixed connection that fixes the face contacting and non-face contacting sides in an operative position and thereby securely encloses the respective one of the pair of rigidizers between the face contacting and non-face contacting sides. ### Claim 2 (depends on 1) The respiratory mask according to claim 1, wherein each of the pair of rigidizers includes a rear end portion, the rear end portion of each of the pair of rigidizers including a slot structured to connect to a headgear strap. ### Claim 3 (depends on 2) The respiratory mask according to claim 2, wherein the rear end portion and the slot thereof of each of the pair of rigidizers are structured and arranged to guide the headgear strap over a respective ear of the patient. ### Claim 4 (depends on 1) The respiratory mask according to claim 1, wherein each of the pair of rigidizers are adapted to extend from the airway interfacing portion, over a patient's cheek, and to a location at or adjacent a patient's ear. ### Claim 5 (depends on 1) The respiratory mask according to claim 1, wherein the face contacting side of the cover is constructed from a different material than the non-face contacting side of the cover. ### Claim 6 (depends on 1) The respiratory mask according to claim 1, wherein each of the lateral edges of the face contacting side is directly sewn to a respective one of the lateral edges of the non-face contacting side. ### Claim 7 (depends on 1) The respiratory mask according to claim 1, wherein the cover is arranged to prevent removal of the respective one of the pair of rigidizers along an axis extending perpendicular to the face contacting and non-face contacting sides in the operative position. ### Claim 8 (depends on 1) The respiratory mask according to claim 1, wherein the cover comprises a fabric or fleece material. ### Claim 9 (depends on 1) The respiratory mask according to claim 1, wherein the cover includes a multi-layered construction including at least first and second layers of material. ### Claim 10 (depends on 1) The respiratory mask according to claim 1, wherein at least a portion of the respective one of the pair of rigidizers is uncovered or visible when the cover is assembled onto the respective one of the pair of rigidizers. ### Claim 11 (depends on 10) The respiratory mask according to claim 10, wherein at least the front end portion of the respective one of the pair of rigidizers is uncovered or visible when the cover is assembled onto the respective one of the pair of rigidizers. ### Claim 12 (depends on 10) The respiratory mask according to claim 10, wherein each of the pair of rigidizers includes a rear end portion, and the rear end portion is uncovered or visible when the cover is assembled onto the respective one of the pair of rigidizers. ### Claim 13 (depends on 1) The respiratory mask according to claim 1, wherein each of the pair of rigidizers comprises a curved shape. ### Claim 14 (depends on 1) The respiratory mask according to claim 1, wherein the airway interfacing portion includes a frame and a cushion. ### Claim 15 (depends on 14) The respiratory mask according to claim 14, wherein the front end portion of the respective one of the pair of rigidizers is structured to connect to the frame. ### Claim 16 (depends on 14) The respiratory mask according to claim 14, wherein the front end portion of the respective one of the pair of rigidizers is integral with the frame. ### Claim 17 (depends on 1) The respiratory mask according to claim 1, wherein the positioning and stabilising structure further comprises headgear straps provided to the pair of rigidizers. ### Claim 18 (depends on 1) The respiratory mask according to claim 1, wherein each of the pair of rigidizers includes a rear end portion, and the cover includes a rear slot to allow the rear end portion of the respective one of the pair of rigidizers to extend therethrough and connect to a headgear strap. ### Claim 19 (depends on 1) The respiratory mask according to claim 1, wherein the airway interfacing portion includes a frame and a cushion, and the positioning and stabilising structure is structured to connect to the frame. ### Claim 20 (depends on 1) The respiratory mask according to claim 1, wherein only said lateral edges of the face contacting and non-face contacting sides are directly and fixedly attached to one another. ### Claim 21 (depends on 1) The respiratory mask according to claim 1, wherein the
