Solo campers in places safe from brown hordes can use a very warm sleeping bag and a sleeping/tent hammock. Make sure you get very good at lighting a fire before you go. Simplify food by eating high protein and light. If you are buying hiking boots always go 1-2 sizes too big. Feet swell a lot and hiking socks should be thick. Make sure the sole of your shoes is not too rigid. Wool is always the best. Carry a whistle. Make camp well before dusk, the night is when danger rises. Snickers bars are great emergency food. Super high calorie and very light. It’s worth it to carry a sketch pad, a whittling knife and a few books. It’s wonderful out there. Enjoy!
