I don't think there are any, beyond the "Anonymity Hood" that Thieves can start with. It's a real bummer. There is a really sweet Light Armor hood, they need to move that model over to Medium, or something like it.
I checked out the Whisper Hood, and it is a mask, it's a bit more like a classical ninja mask, but more embellished in a kind of Arabian style. I really just want the light armor hood remade as a medium.
