>>343565Aside from the fact that OP pointed out that it's not more expensive (unless you already have "heavy" gear, in which case yeah, you'll have to buy it all again), it's also quite a lot about saving money.
I'm not an ultralight fanatic myself, but still, plenty of their tips simply make sense and either don't cost you a think, or make you save money.
I still remember when I associated camping with "tents", "aluminium water bottles" and "gas stoves". Now I'm under a homemade tarp that cost me $10, most often in a homemade hammock that cost me a total of $20, I use simple plastic bottles for water, and I switched to a "no cooking" diet that only requires some heating at best, which can be done over the smallest fire of needles and dry leaves. Without being obsessed with the weight of my backpack, I made it lighter by some 4kg, and it cost me nothing seeing as I sold my old gear.
Oh and I saved money by learning to buy "microfiber mops" instead of "microfiber towels", which I learned are the same thing, and I saved money by buying a cheap Chinese LED flashlight on eBay that's lighter, sturdier and brighter than the one I wanted to get instead, and I saved money on my sleeping bag because I learned all the insulation in your back is essentially worthless...
You have no idea how most ultralight walkers are actually real scrooges and want to travel as cheap as possible. As for the picture you're mentioning, I'm the one who first posted it on /out/, and here's the description that comes with it:
