I try to keep my pockets fairly empty, usually just a folding knife, lighter, and cell phone. My bino harness carries everything else, and is something that is always on me. In there I have wind checker, ear plugs, lighters, extra ammo, lens cloth, tags, Garmin Inreach mini, Petzl e-light, bandaids/aspirin/advil/water tabs in a vac sealed pouch, and a honey stinger waffle w/ some Justin's PB. There's usually a pistol on the harness as well.
This all fits in a AGC Cub Max, and has been relatively unchanged for the last few years. I try not to leave my pack or get separated from it, but with what I have in the harness it's not the end of the world to be away from it for a few hours or most of a day.
