While working in the field at night, or under poorly lit conditions, the ability to identify friend from foe can be crucial to that split second decision. The infrared reflective shoulder flags make distinguishing whoever is in your sights that much easier. They come in large (2” x 3.5”) and small sizes (1” x 2”), and in convenient 1” and 2” squares, should you be required to sport a specific design of IR tags. Don’t think that IR reflection is restricted to military use however. Firefighters and rescue workers using infrared imaging equipment may find IR reflection particularly handy while working in or around smoke-filled environments, since smoke is more transparent to infrared than to visible light.
