Using the most retro-reflective material, Reflectacles Ghost reflect both visible-light and infrared-light*. Cameras using infrared technology will not be able to capture your facial features. They also reflect visible-light making you seen on the road and anonymous in images/video using a flash. (Note: The reflective material for Ghost is only available in silver)
* Apparently the material reflects the whole light spectrum from gamma rays all the way to extremely low frequency, but I will leave that with you to test out if you want to. I know it reflects from visible to infrared.
Reflectacles Originals reflect visible-light making you seen on the road and anonymous in images/video using a flash. They are available in seven colors. The order from most to least reflective are:
