From 1999/2000 era. I purchased these in Los Angeles originally and were worn very infrequently and stored. Nice piece of Levi’s history. Lace string and inside pockets still maintain original cotton color. This style was meant to fit ergonomically. Probably even rarer to find in this size. From Levi’s website: “Twenty years ago, we introduced Levi’s® Engineered Jeans™, an innovative approach to denim that used twisted side seams and a darted yoke to create a more ergonomic fit. The idea was that by taking a forward-thinking approach to design, we could maximize both comfort and freedom of movement. When we launched the line in 1999, they were a huge hit — not only for the way they fit, but also for their progressive style — and they’ve been something of a legend ever since.”
