It seems that most of the sleeve manufacturers don’t like making sleeves for the 10.5” Pro that accommodate both a
MoKo TPU back cover (with corner bumpers so a bit bigger) and an Apple Smart Keyboard.
I bought a ProCase sleeve that fits the above pretty well, a little tight at the corners (due to the bumpers) but otherwise good.

However, while the ProCase protects everything well, it’s a bit bulky for my preferences for everyday use. I’d like to get something thinner. I bought the tomtoc sleeve but it only works well with a naked 10.5” Pro, even though they claim it is compatible with the Apple Smart Keyboard, and compatible with the wider 11” iPad Pro too.
With even just the Apple Smart Keyboard it doesn’t keep closed consistently, and with both the Apple Smart Keyboard and the Moku back case on it won’t stay closed at all.
Hopefully the rejuvenation of this form factor with the release of the 10.5” Air (which is also ASK compatible) will induce the sleeve manufacturers to accommodate this type of setup.
