My best guess (not in the community or anything) is that leather does better at being durable—especially if you treat it well and condition it regularly?—than cloth and plastic-leather alternatives, which break down. I know leather is meant to be very durable and have good “properties,” but I can’t be specific.
I hate that feeling of knowing I need to do something and wanting to start, but actually doing it is like my body and mind are weighed down by concrete.
