not sure what a harness is, but full plate cavern crawling, sure I can go with that easily. I'm just putting a limit when its massively bulky or massively heavy, then its pretty hard to make a movie depicting that. I was just saying a vlog showing medieval arms and armor, backpack, provisions would be cool to set a rough ballpark. Probably someone already made one.I'm really not sure which direction you are trying to argue. I'm simply listing a constraint on the Original Post's primary question.
If you can't believe Gandalf carrying 500 lbs of loot, can you believe a heroic fighter wandering into the wilderness in full harness without horse and retainers and crawling into caves and caverns? If so, there is probably going to be a place where you will have to define what level of realism you desire.
