It depends on what I'm doing and what time of year it is.
At home while deer hunting, I carry a small fanny pack and that's about it. It will have my license, a small flashlight, a gutting knife, book of matches, a facemask, and a compass. Late season, I might put in an extra pair of gloves and a warmer.
When doing a multi-day hunt out west or something, I carry my big backpack with all of the stuff listed above, plus extra water, food, TP, bivy and sleeping bag, tarp, extra pair of socks, and another couple of layers that I can put on if need be. I'll also carry a Zoleo for emergencies.
