Been field testing my new Velcro backed Zero Dark Glow Tab from snakedr666 today, and I’m very impressed so far. I’ll be attaching it to my bag for increased visibility on my evening run. 

I have no idea what the material is, but boy does it cast a mean glow -
Only 9 of these were made and I feel privileged to have managed to get my hands on one.

Seen attached to a Mini SERE pouch from law66, with a Disruptive Thinker Morale Patch, and break-away lanyard from SnakeDr for neck carry.
