Say it was nighttime and I was wearing all black polyester clothing, how much more visible would I be than if I was wearing all black cotton? Cotton seems to have more of a flat color and seems like it would be harder to see at night. So the question is, how much more visible are you with the polyester?
It all depends on the thread and weave of the cloth. It can be made anywhere from a dull finish to a high-gloss finish.
