I've never known what this one was called, or even what comics it has appeared in. I'm fairly certain it has appeared in something but I don't know what. it looks a lot like the Neal Adams 70s Batman costume, same belt, same bat symbol, the only difference being that the cowl, cape, boots, gloves and underwear are all black instead of blue. everything else is basically the same, that's really the only change. the only place I remember seeing something like it is on the cover for the Outsiders Convergance book.
only there's still very clearly some blue to it, its mostly black here. that's the closest I've come to finding it in a book. does anyone know what this costume is referred to as?
