BOB...Bug out bandana

[Prepaday]

when TSHTF who do we trust? How do we figure out the good guys from the bad?
If something happens to me, who could I turn to?
Here is a scenario... I have prepped for years, put a plan in place yet my bol has been found by the bad guys and for some reason, I couldn't defend myself properly(no g un)
I wander around the countryside in fear, alone and hungry.
I hear a noise and hide, A large, burly man walks in my direction with a g un, All I have is a sling and a few jagged rocks at my side, Is this guy a prepper or a baddie? How do I tell?
This morning I had an idea... How about if we wore a bandana that let others know we were the good guys?
The bandana would of course be a useful one, lightweight yet you could hang small items from it, Hide small items in it or have a waterproof membrane for collecting water it could also have a use as a bandage, sling etc, Just a few ideas for a preppers bandana.
The bandana would come in a few colours for camouflage.
Maybe the bandana could have a small logo/ coat of arms on the front so we would know who to trust should TSHTF?.
I can rustle up a prototype and make a vid to show its usage if anyone is interested?
