I got your patina right here…
Nomad CXL folio for my XS -- purchased Summer '21 and now going into retirement with the phone.
I have their case for my iPad as well, and it has also been great.
But the phone case is even greater because I bought it for $4.95 on clearance sale. The $9.95 shipping charge was double the case!
What fell short for me were the poor (integrated) button action (seemingly rectified in their newer cases) and lack of sleep/wake magnets in the cover. I had another folio case with them, which was very handy and no issues, but some experience interference with the compass or haptic motor in their presence.
The leather adjacent to the fold didn't start to peel until later in its tenure, but given the stress it's under, acceptable. Otherwise, I've found Nomad cases don't delaminate.
I'm going to order a successor for my 17P before the BF sale is over, and take a chance on the ECCO version. As much as I like CXL and its intoxicating smell, I'm trying to be practical and $87+tax for a phone case, no matter how nice, is pushing it beyond where I want to go. Almost bit on the limited #8 color during the deal of the day, when the discount was 30% instead of 20%, but the extra $10 upcharge for the special color was another turnoff.
