I have been using the Carradice Super C Rear Panniers for a few years. My previous set of nylon panniers from another maker had issues with the connection of the panniers to the rack, but the Carradice have a sturdy connection system. Also, the Carradice panniers are made from thick canvas. This came in handy when I accidentally hit a sharp bolt protruding into the road. Nylon panniers would have been permanently trashed, but I was able to sew the Carradice panniers with sail thread and they still work great. I highly recommend these.
