A conformable wound dressing system that includes a backing and a dressing support layer. The backing has a first major surface, a second major surface opposite the first major surface, a perimeter that includes first and second lateral edges extending from a first end to a second end, and a longitudinal axis extending form the first end to the second end. An adhesive is on the first major surface and a dressing support layer is on the second major surface. The dressing support layer has a first section and second section where the first section is disconnected and spaced apart from the second section to define a gap extending from the first end of the backing to the second end of the backing.
