Same as your ones you have on the back... not breathable. I believe that the one you found: "Ortlieb Sport Roller City Black Saddle Bags 2016" is simply a different year of the same thing as "Ortlieb Back-Roller City Rear Pannier" in my link. Comparing the two, I see that the mounts are higher, and therefore the bags would sit lower in the 2016 version. Is this a good thing them sitting lower? Probably depends on the rack.
