I’d recommend Rite-in-the-Rain. I spent about 10 years in the Army, and those were the only products I’d trust to survive. The notebooks and especially the paper are designed to work in the rain, the mud, the dirt, etc. I don’t think any of them have ever broken or worn down on me in that time. I still have all of them to this day. I think I’ve had some of the notebook “cases” for around 12-13 years and they’re still in good shape.
