Sorry it took so long getting back to you. These are expensive bags, I think I've got $800 US in them, that includes the Easy Brackets. They are made in Germany and very superior quality. I bought them in the summer of 2003, as you can see they have held up very well. They are made of farely stiff saddle leather and have kept their shape well. The leather is water proof, I just wipe them down with a damp cloth to clean.
They are 32 inches wide, mounted accross the bike. Each bag is 20 inches long, 10 inches wide, and about 12 inches deep. They are 30 or 31 liter bags. They are lined with thin foam and the mounting or back side are a thick plastic of some kind, no reinforcing required to mount Easy Brackets. I am going to try a link to a slide show, wish me luck.
