Quality of the bag (s) is excellent in wet conditions and rain, everything is inside dry. The design and materials are excellent, even PVC free. Security Cable I find great, but I would wish me the opportunity it shut equally, not just a loop. Use it with a small suitcase lock and close it from the luggage carrier. The inner workings could be more exciting, that is perhaps more subjects or extra pockets, such as in Samsonite suitcases. However, since the bags fulfill their function, by me 4 stars.
