Have two sets of Jandd bags. Expandable Mountain Expedition...NOT waterproof. Saddlebags...not waterproof and not very roomy. Stick w/Arkel or Ortliebs...There's another thread on here recently where someone found a set of waterproof panniers for under 100.00 w/free shipping. Can't remember the brand name, though. It was only a few days ago, so maybe you can scroll back through the threads. Anyway Jandds are very overrated and the only reason I got them was I didn't know any better. I still use them , but I'd rather get a better set...fundage, fundage.
