An adjustment system includes: a first strap assembly and a second strap assembly positioned 180 degrees with respect to, and entwined with, the first strap assembly. Each strap assembly includes a slider having first and second slots therein. The slots are defined, in-part, by a central portion extending between both of the slots, a first end portion extending along the first slot opposite the central portion, and a second end portion extending along the second slot opposite the central portion. Each strap assembly further includes a strap portion having a first end coupled to the second end portion of the slider and an opposite second end structured to be coupled to one or more of the patient interface device or another portion of the headgear; and a tab coupled to the first end portion of the slider, the tab being structured to be grasped by the patient.
