VIRTUALLY INDESTRUCTIBLE: The Expedition Edition Field Notes book features their signature untearable and virtually indestructible paper. To get here to this note book perfection, Field Notes explored a wide variety of papers, colors, and printing techniques, and with this new Expedition Edition, for the first time, the kind of paper used in their notebooks was actually expanded. Aesthetically, you’ll find an all-new design with plenty to like: a hi-visibility “Antarctic Survey Orange” on the front cover and “Polar Night Black” back cover, with a subtle varnish effect featuring a topographic map of Antarctica. The body pages feature the popular dot-graph paper printed in light gray. The real innovation here is, of course, the paper. It’s maybe not even fair to call it paper. The whole book is printed on Yupo Synthetic paper, an amazing tearproof and waterproof paper extruded from polypropylene pellets in Chesapeake, Virginia. We could go on and on about this notebooks’ durability and incredible properties. It’s even been scientifically tested in a series of studies regarding waterproof, visibility, ballistics, vacuum, tensile strength, compression, acid resistance, temperature, electromagnetic waves, and electrical resistance. Months of development and testing were required to get these books just right, and Yupo provided a lot of support for the extensive work, as well as all the great printers and ink technicians that pitched in to help. A majority of customers may not test the limits of these notebooks, but the map of Antarctica is neither hyperbole nor coincidence. This Expedition Edition was sent to the South Pole with explorer Ben Saunders as he and his team retraced Captain Robert Falcon Scott’s ill-fated journey to the Pole and back, on foot and unsupported, in October 2013. Note: Synthetic paper is nonporous and doesn’t absorb ink like our conventional papers. Ballpoint pens, pencils, or fine tip Sharpies work best.
