I recall going light, as a young man, packing a military fanny pack, a space blanket and a wool blanket, a fold over grill, with steak and ham steak for breakfast, build a fire, and voila, the plastic “army” canteen, fit in a cup with handle, and that was what I made my soup in. Froze my ass off one night in the high mountains! Another time, I got a brilliant idea to take only a pair a lightweight karate pants, and got hit by hail, in July or August (high Uintahs), I used to carry a tent fly, silver/aluminum, no idea what it was made for, but it was some kind of smooth on the top side, almost reflective, some cord, and a handful of cheap aluminum pegs, tie it off to two trees, or one, and steak it out, use my poncho for a ground cloth, and did that a few times. Sadly, got a bivvy “tent,” but the dogs got eaten by a fluke of mosquitoes, this last time, starting to go up on weight, just got a sierra west, though I would get a fly for it, and give it a try, and I also got me a clip flashlight! there was another smaller two hoop tent, by sierra, but it was only about 20 square feet, and the dogs are too tight in a small tent like that, with me. looking at a eureka now.
