I bought this cover from Custom Covers for my Moog One and I am very happy with it. It fits well and has a cutout for cables.

It doesn't have a Moog logo, but you can get custom logos (send them your PNG file). But they can't do trademarked logos without permission from the TM holder. You can also get it without the label and save a few bucks.
These are padded covers with velvet soft cloth inside and tougher nylon material outside which offers a little better protection from falling objects, animals walking across the synth, as well as resistance to liquid spills. It does not let any dust through the material as mentioned about many of the single layer unpadded cloth covers.
Anyway, I have a dozen of these covers for various synths and I have been very happy with the fit, construction and the price.
