The Dux rugged case is made to just snap right on the iPad Pro, and it not only protects the device but has a place to hold the Pencil. I’m talking about that cool accessory that Apple just released, but I just checked, and it will hold a regular pencil too. By the way, this particular iPad accessory is made to work with Apple’s Smart Cover as well as the Smart keyboard.
It is a rugged case, and it only protects one side (the back), but that’s good enough for US military standards. The material is described on the STM website as translucent, but if they are referring to any part not the edge, it looks more transparent than anything.
So yes, the STM Dux iPad Pro case is just what you need for some protection, and it is available for the iPad Pro 12.9 and the 9.7 inch versions for $59.95 on the STM site in black only.
