The disclosed medical dressing has at least two thin film backings in overlapping relation to one another. The backings entirely surround an opening to form a window. In one embodiment, the first and second backings are a conformable film each formed in a generally C-shape such that the open ends of the C-shape are laterally aligned with one another and form an opening at least partially surrounded by the first and second backing. In use, the opening generally is aligned with a wound. The medical dressing, being constructed from at least two backings, allows for control of the desired opening side during application of the backings by overlapping portions of the backings.
