There is one thing 5.11 makes that does not scream "I am a wanna be seal" and that is some of their jeans lines. There are a couple of extra pockets along the hip line that make a great storage place for a thin wallet, cash, or electronic key pass. I have a number of them and the 5.11 logo is so small that people never notice and they are very comfortable. Watch out for their "slim fit" as the legs are really snug and evrey time I get out of a chair I would have to bend over and pull them down.
Paired with a simple vest and you are good to go.
