Is this stuff just super reflective, or does it have to be charged?
I've got one reservation about luminescent markings that have to be exposed to light to work- the inside of my pack is probably pretty dark. I don't fit in it, so I can't be sure, but unless there is a gremlin with a flashlight I keep missing anything that needs light to glow isn't going to be glowing when I need it.
