Who makes the lightest possible iPad Pro front cover-only case?

This is a moot question since there is only 1 cover-only for iPad Pros... Apple's smartcover. (unless I'm misunderstanding what is being asked)

 

Starting with the iPad Air 1 there haven't been any aftermarket smartcover-type covers. I believe that it has something to do with the hinge mechanism of the new smartcovers. Before the Air 1, the hinge consisted of swiveling metal parts, but this new hinge is a magnet with a rubberized coating... I suspect that it is protected by patents.

 

Here’s one for the 12.9 inch. There certainly aren’t very many but they are out there. Haven’t a clue what it’s like but at that price it’s probably a bit pants. Personally I’ve never found anything that comes close to the quality of Apples Smartcover.

The current Apple Smart covers are way better than the 1st gen ones. The first models had metal connectors that scratched your iPad and the cover was very thin. This gen is little better. If you look around Amazon and other resellers, they will put them on sale. I grab one for $20.
