During season five production and filming (mainly on-location filming), these T-shirts were worn by Crew members to identify them (much like a "Roadie" at a concert). As the image shows above, it had a simple logo on the back of a regular black T-shirt. The image is a bit misleading, however. The logo was in fact not orange, but rather a blue-ish reflective material that somewhat sparkled in the light (the flash of the camera just made it appear to be orange).
