I get obsessively cutting weight and volume, but WOOL BLANKETS are the ultimate reason for doing so, not so you can walk around as close to unencumbered as possible through the woods like a little faggot on your backpacking tour. You spend 4+ hours a night sleeping, is the pack space really that important that you need to do it in a smelly, sweaty synthetic cocoon? Fuck you people are plebeian.
Extra bonus, wool blankets are also excellent clothing in all weather. Fuck yourselves, go raid grandma's house for some wool.
