It's my understanding that felt is now considered by some to have been an apporpriate material for 'underarmor' padding- not modern stuff but the old, long-fiber matted, not rolled under a massive press kind. It's supposed to be quite breathable and yet provides good blunt force protection. Encase that in some not super-tight weave linen canvas so as not to comprimise the breathability, and it sounds good to me.
