>>639423Ultralight is such a bullshit hipster terminology.
This is what a historical "ultralight" equipment looked like.
If you look at mountain man packs they're lightweight too. If you need to haul gear you get a pack animal. These were people who lived in the wild.
Most of what you need you can make. All of them would have carried butane lighters if they could, but you'd die when the gas ran out or lighter malfunctioned while they could just make primitive style fire as always.
If you know your basics you can craft almost everything you need.
