Also just arrived is the Mous Super Thin in black. I ordered this on a bit of a whim when ordering the above Limitless case as I've often enjoyed very thin cases but not found one I like for the 15 Pro. My initial impression is excellent - it's a lovely feeling material, comfy to hold/rest on pinkie, and I've always enjoyed thin cases like this that just have cutouts for all buttons, obviously I know many don't so YMMV.
There is a small amount of case higher than the screen for protection when placing face down, I've tried to take a close up side on to show how much. It's minimal, but I personally accept this when using thin cases like this, I don't think many have both.
I'm leaving my Limitless on the phone for now, but will try this too in a few days.
This year I tried thin cases from Nudient, Bare, Torras, Totallee and Peel, and this is the best of the lot IMO. I'll be keeping it for sure - I always like to have at least 1 very thin case in my 'stock', and this will be it for the 15 Pro.
