I have settled with this case for now. Keeps thinness profile and feel there's some protection during falls.
The 950XL has been out a good while now and the case selection is, TBH, poor. Is it likely there'll be any more variety in future, or is that it for this model?
It looks like leather but is really more like silicon. It does look slick to me.
That IMAK PU leather case looks really nice, except it looks like they forgot to put the holes for the microphones on the top and bottom of the back from the pictures.
