To me the differences in leather in different panels is one of the cool factors of leather. It's always evolving.....give it a month and it will change....lolMy new Eastman horsehide G-1 has the exact same mismatch where the outer sleeve panel has a ton of grain and wrinkles while the inner panel is pretty smooth and boring. I only noticed this the other day after wearing the jacket nonstop for couple weeks since I received it.
This doesn't bother me since they put the boring leather where it was pretty unnoticeable, perhaps there is a method to their madness.
