That's the great thing about the Ortliebs - barring complete immersion, those things will not let in any water, period. So - what's the deal with cotton duck?

Edit: Found this thread, in which some people seem to say that the bag is effectively 100% waterproof (Scotland does get pretty wet), while another person says that stuff inside can get kind of damp:
