In reply to Russell Lovett:
OS map with the cover carefully removed in an Ortlieb map case. I tend to hold a map while I walk (rather than keeping it in a pocket or whatever) so even if its not raining the case stops my sweaty paws from unnecessarily damaging the map.
I've tried laminated and waterproof maps but I find them hard to handle. Printing my own is a faff as well as limiting if I want/need to change my route.

Maps get out of date, and I personally think its best to treat them as something to be replaced every few years. For this reason I I don't worry too much about keeping them in good condition, and I prefer conventional paper maps that are cheaper and can be easily recycled.
