The waterproof covers do have a use. Put them over the bags when not in use in your garage on the shelf. No dustOh let me add a 4th crapola factor- the so-called 'rain covers'you speak of.. Ahem...they cover most of the panniers EXCEPT for the inside of the panniers.. you know, the tire side which is like a fire hose throwing water into the panniers. No I'm sorry my friend, these suck big time. On the other hand, I am completely ecstatic over the bike itself. Without a question the best steed I ever rode.
