I’ve got wallet and lighter front right, phone and cigs front left, and keys on a carabiner tucked into back right. Back left is basically always empty.
Phone in front right, wallet and keys in front left. When I'm not at work, that's basically it.
I wear a small satchel at work; I keep a water bottle, clipboard, and notepad in the main storage compartment. My satchel has a few side pockets as well; one holds my pens and markers, the second holds a box cutter and a pair of gloves, and the last one holds a small first-aid kit.
