The saddlebag act as a compressor, it work brilliantly once it packed and tightened properly, so you may need extra care to make sure it's tightened appropriately.
Fortunately it's something that you can get used to and able to get better with more experience, the saddlebag I got is from Revelates Design which have a strap inside to keep the stuff compressed while being able to access the saddlebag.
