Hi everybody. Currently I'm looking for a new pair of rear panniers. I like Vaude Discovery Pro and Ortlieb Back Packer Plus. I wonder how does this Cordura stuff compares to shiny polyester products (such as Vaude Trans Alp or non-Plus Ortliebs) in pouring rain? Can it survive lets say a whole day of non-stop rain?
And how do they cope with ventilation? Are they as sealed as the 'rubber' versions?
