Damn, those masks sure are expensive. Whenever I spar with my home-made wooden swords, I just put on an old motorcycle helmet and some gloves and I'm fit to go. It's a good way to simulate medieval helmets too, since I imagine that my visor is open. Besides, getting smacked over the head barely hurts when you've got a motorcycle helmet on. And I'm talking about those full-faced ones, not the ones that leave your face open.
