I was looking for the 557 version---my favorite jean--and apparently these 527s are supposed to be a replacement.  They are way too slender in the thighs, to the point that I can't even put them on.  I'm not a heavy guy, but right now these have yet to be worn and are waiting to be tossed out.  They'll probably end up at the donation box unless they can be stretched or I can lose 20 lbs.  I'm still not sure I could wear them. AND the material they use isn't like the old kind.  They just feel cheap.  I guess this is how things are these days.
