Headlamp, GPS, some rope, 3 pillowcases (game bags), small first aid kit, 2L of water, sandwich, lighter, some TP, knife, rubber gloves (3 pair) and a compressible down sweater as an extra emergency layer .... the more I carry the less ground I can cover. I prefer to keep it to a minimum.
If I'm day hiking but with the possibility of spiking it for the night then that's a different story. Then a few extra items get tossed In like sleeping bag and glassing pad and a tarp.
Not carrying fuel or a stove or any of that. That's just too much weight. Dont need a hot meal every every day.
