I have worn these jeans for years, and they were always made with 99% cotton and 1% spandex.  I had read reviews that the new fabric blend was not so great but thought I would give them a try since Lee is the only brand long enough for me (at a reasonable price).  Well, I must concur with the negative reviews.  The fabric stretches way too much.  It is thin and cheap-feeling, and the zipper is poor quality.  If you have a tummy, they are very unforgiving.  They are comfortable but they just don't feel right nor look good.  I don't think I will buy any more if they are going to keep this fabric blend.
