Can't say enough good things about the Traveler's Notebook.
- It's rugged.
- It's modular.
- It improves with age.
In addition to all of the customization options, it's about the same size as a reporter's notebook, which fits nicely inside the cover. Also, if you're into fountain pens, the elastic band does a great job of keeping it in place along the side.
