I did some searching but some fresh opinions would be greatly appreciated.

I'm in need of a sturdy medium sized backpack for a GHB. I have a few other setups but they are more of the tactical type, and they would probably scream "shoot me I have cool stuff" in the event I'd have to hoof it home.

Simple criteria here:

Well made and sturdy
No MOLLE webbing, or very minimal
Not in a camo pattern or military color (no coyote, etc, a dark green or grey is my preference)

There are a good amount of options out there that I am looking at but if anyone has any experience or advice, I would be grateful.
