@Nine @cozykaffe@snouts.online I imagine it wasn't as heavy as full plate armor, either, though what amounts to a few dozen phonebooks strapped to you is probably far from weightless.
I think the mythbusters did an episode on paper armor once, though I don't remember the results.
@Rosemary @cozykaffe I think mostly it was designed to protect against a hail of arrows because they certainly had an awful lot of archers. And for that purpose, fantastic.
