Abstract
A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a headgear assembly removably attachable to the frame. The headgear assembly includes a pair of side portions and a rear portion that interconnects the pair of side portions. The pair of side portions includes at least one strap. The rear portion has at least one strap constructed of at least two layers of material. One of the layers of material has a more rigid construction than the other of the layers of material to resist compression of the at least one strap of the rear portion in a first direction which resists movement of the at least one strap of the pair of side straps in the first direction.
