i came across a strange notepad when I went out on a hike once in the nature reserve gift shop. a notepad simply titled "rite in the rain". its paper with a hydrophobic coating made to solve the "people working in logging or other outdoor careers back in the past needed to be able to take notes in a variety of conditions and need paper more resilient against water damage." problem, at least according to the short history blurb on the back. I'm unsure if its patented or not. I've certainly never heard of this because who tf needs a water resisting notepad these days.

its not bullshit, I ran a page under a small trickle of water and watched the water bead off the page rather than soak and destroy it.

if its wet, you can write with pencil, wax crayons, etc. pens will work when dry.

its the basis of my current tome loadout.
