"... wind frequently makes paper maps hard to use!..."
The big OS sheets are unmanageable in "weather", worse still if your route involves two sheets. And the plastic laminated versions although waterproof, are rather bulky.
I use desktop OS mapping (not the OS app but the vastly more versatile Mapyx Quo) to plan my route then print the relevant area (usually 1 or 2 A4 sheets) and take in a plastic A4 envelope. That's easier to use than mobile as a primary navigation aid, the mobile can be helpful where the path isn't obvious or you need reassurance about exact current location. Printing also means you can enlarge from original paper map-scale making it easier to read.
