Gore tex is (a) bloody expensive (b)for luggage.. pointless..... it's no more waterproof than pvc, it's just breathable.... so if your gear has a sweating problem... perfect
As far as North Face gear bags... i own one and though the design is good the fabric is rubbish compared to what it could be(for the $). they are made of the lightest possible grade Truck tarp material. If you went to any horse saddler or Auto upholsterer, they could turn you out something custom made for the task, of more durable material, and without the thief attracting logo's. all this for half the price.(if not less than that)
Amybaja used some ortlieb bags to ride through Africa. I spoke to robboxrv (her travel partner) about them and he reckoned they were very good
Hope you find something that suits
