Anyone test out one of those neoprene or other zippered travel cases that I can slide the iPad Pro inside with the Smart Keyboard and Khomo back cover on it. When traveling I want to be able to toss this in a back pack or carry on luggage and not worry about damaging anything. I'm sure the Smart Keyboard and back cover can take some abuse but those zippered sleeves are padded and make me feel better. Anything on amazon? Thanks.
