Machined out of aluminium, brass or titanium, Exovault cases are about as masculine as iPhone accessories get. I'm struggling with to find a catchy name for style of product, but I think I'll settle on "postapocalyptipunk." Or possibly "Zunepunk."
I can see a few potential problems here, like poor heat dissipation, iPhone scratching, excessive weight and general discomfort during use and carrying, but if you're the kind of person who sees the Exovault and thinks "awesome," you probably don't care. Cases ground out from the lesser metals are available for $US95 each, while the titanium version sells for a sky-high $US300. [Exovault via BoingBoing Gadgets]
