The Field Notes Expedition was not well received as the paper does not agree with many pens. The Expedition edition uses a synthetic plastic paper and cover which makes the pages and cover tear resistant and waterproof. The pages have a grey dot pattern. I haven’t used any other waterproof papers so I don’t have anything to compare it to but I really like these Field Notes .
As you can see below, this paper is not the most pen friendly. I have found that regular (non-gel) ballpoint pens and pencils work the best. Writing in the notebook feels like writing in cold butter; it is so smooth and pleasant that even the finest points feel great on this paper. I dipped the notebook in water after doing a smear test and the plastic pages were completely fine, however, most of the ink was not.

1. Zebra Arbez Piitro Ballpoint – Smeared but not affected by water
2. Field Notes Brand Bic Clic Ballpoint – No smear no issues with water
3. Pilot G-Tec-C3 Gel Pen – Smeared but not affected by water

In addition to the Field Notes Bic Clic pen below I have found that the Pilot Down Force, Lamy Dialog 1, and the Parker Jotter all worked well on this paper.
