Adventure Paper

If you're the hardy outdoor type, a person who loves hiking, sailing, mountain climbing, or other nature-filled activities, you'll often need a map of where you're going. Unfortunately, in the intense conditions you'll be in, regular paper just won't cut it — it'll get wet, the ink will run, the paper will tear, and you'll be out of luck. Adventure Paper aims to make these inconveniences a thing of the past: it's waterproof and tear-resistant, so anything you print onto it, map or otherwise, won't run or get destroyed if the paper gets wet. $19.95 USD.
