Okay I have looked (not long and in depth) for a cover, I love my Field Notes and carry them daily but am looking to add some durability to them. Who knows of a nice Bison (I like bison) leather cover that will fit a variety of Field Notes style books (Rhodia, Moleskine, Shinola etc) that also HAS to be USA made?
It also has to be thin enough (no wallet built in) and has to have enclosed flaps that will cover the cover of the book (no Midori style).
I also intend on keeping one and one, one Field Notes and one other brand book inside.

Thats alot but maybe there is something.
