These are not the 501s of our youth but they're still Levi's.  The quality of the sewing is not as good as it was when we were younger.  There is much less use of double stitching and the weight of the denim is lighter too.  That said they still size them just as they were when I was a teenager.  It's nice to be able to find 501s I just wish they were built as tough as they once were.
