Like a favorite pair of Jeans, worn yes, but perfect fit.
This is a classic. It's got no useless pockets or wasted space. It acts like a medium duffel, but one that you can backpack. Or it's a tough backpack that's collapsible into a bag or can be rough handled anywhere. Mine came with plenty of signs of wear, but nothing detrimental to the usefulness. I got lucky, mine has all the hardware in tact. It's got character for sure.
I stuffed everything I needed for a four day trip, got it wet in a canoe, and still had no complaints. It's just a good, tough flexible item that you wont worry about if it gets a bit dirty, or takes a tumble, it will handle it.
Get one.. or two use em as transport bags, or pack-em out.
By the end of my trip my companions with packs that cost 10 times as much wanted mine. nuff said!
