Made for people who work outdoors in all weather conditions, this waterproof paper lets you keep writing in the rain, snow, hail, fog, whatever. Around where I live, the only people who'd really need this are the canvassers for political and environmental causes who go door-to-door, like the Sierra Club guy who once showed up in my driveway in a blizzard (that's dedication!).

Rite in the Rain makes a whole line of all-weather adventure journals, notebooks and pens.
