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.

Check out Code & Quill[0]. Their note books are great! Been using them for a few years now.

Leuchtterm 1917 is a nice choice and isn't adorned with "BuJo" noise. I like the one with the dot grid.
