iPhone Xs Leather Case
Another option from Apple is the official iPhone Xs leather case. This is available in a small sampling of colors at launch, but will be available in more colors later in the year as Apple expands the options.
I've been using the iPhone X leather case for several months and I love the look and feel of this case. It's a nice leather that will wear some over time and develop a patina.
If you use it in dirty situations you can expect the color to turn sightly over time. Overall this is a very nice option that will protect the iPhone Xs from scratches and from small drops.
It's only $10 more than the Silicone cases, and a good value at $49.
