I don't tend to worry about what colour arm band I wear, my fat arse can be seen eclipsing the sun at times, if that's not bad enough the sound of what can be described as a pissed up bear stomping through the woods looking for a tree to shit behind would give the game away... an arm band would only alleviate any potential fear my pretend enemies had, milliseconds before firing many 6mm BB's in my direction.
Please excuse the language, me just being me.
