seal lines are bloody good. totally waterproof and the straps are nicely comfotable and adjustable. I also use an Ortleib Messenger Pro, and its pretty hard to choose between them. You can fit a bit more stuff in the ortleib, but it interrupts your field of vision a bit more when looking behind you, and the back padding isn't quite as comfortable imo. I have ridden all day long in heavy rain with both bags and neither leaked.
