soft leather bags will almost always begin to sag and stretch over time if they are not supported by something internally. I have a set that came with my wife's Harley. They are full leather bags.... and sag like crap.
The medium bags I bought for her GZ back in 2008 are in perfect shape, and they've been in the rain a couple of times. They are simulated leather. Not water proof, but I keep ziplocks and walmart bags on all of our bikes to keep things dry.
her luggage looks the same in all photos, but heres about the best/clearest I have.
