The Ortlieb bar bags are waterproof. I use the Classic, and my wife uses the Ultimate 5. We have a lot of wet miles on these bags without any problems. We carry our cameras, phones, wallets, etc, and important papers in them. No special protection other than the bag. The same with their panniers.
We had 35 days of rain on this tour.
My small Sony a6000 fits in the orange case in the middle. The case is just for padding.
