I have a set of them on my bike and I know some other members have them as well. Case, for one comes to mind. I used his pictures mostly as reference when getting my bags. Mine are the 'fullback' bags which basically means they are straight backed. There isn't any sculpting going on to clear guards,brackets,ect. Been really happy with them so far and they hold a ton of
cr@p for sure. Oh wait, the standard for size measurement... they will easily hold a case of beer, not cans mind you but longneckers each. Never had cans in them but bet you could hit the case and a half mark with them.

(sorry the pic isn't a side shot, but it was mostly about the seat. Anyway I don't remember seeing any pics of them from the top down anyway so this can better give you an idea of the size)
