Built for rough conditions, the Field Notes Expedition 3-Pack uses waterproof and tear-resistant Yupo synthetic paper. Each 3.5 × 5.5 in (89 × 140 mm) pocket notebook has 48 dot-graph pages and a high-visibility orange-and-black cover.

Are Field Notes Fountain Pen Friendly?

Field Notes notebooks are designed first and foremost for practical, portable everyday use. Ballpoint pens, rollerballs, mechanical pencils, pencils, and fine-tip pens are especially well suited to them.

Fountain pen performance varies by edition, paper, ink, nib width, and ink flow, so we do not recommend treating Field Notes as a dedicated fountain-pen notebook. Fine and medium nibs may work well on many editions, while wetter combinations can show feathering or bleed-through. Expedition's synthetic Yupo paper is not suitable for fountain pens.
