A headgear assembly includes a strap of a first flexible material with an elongate edge, and a second flexible material folded around and running along the elongate edge. The second flexible material may be an elastic material. The second flexible material may also cover an intersection or joint in the first flexible material such that the first flexible material may be made from two flexible materials layered together or joined end to end.
