Will you ask them if they have a photo of the 25l top box showing the dry duffle bag from the front? I am wondering if the top box is mounted far enough back for the wife to use the dry bag as a back rest. I don't think the 25l alone would work as a back rest.
I have this narrowed down to the 38l bags. Just need to figure out whether to go top box or not.
