I've seen a couple of vids mocking this style of fashion. It really is no different from any other "high" fashion fad, it's almost exclusively about wearing expensive shit that you know other people know is expensive."Techwear"
A community of people who really want to dress like they live in a futuristic cyberpunk dystopia. Sort of like the people who want to dress in tactical military gear...but for nerds.
That said, if someone gifted to me a techwear piece, like a cool waterproof jacket or something, I wouldn't really mind.
