I purchased my first pair over a year ago, they surpassed the rest of my leggings and I now own 5 pairs to get me through a week's worth of workouts. They are the only leggings I own now. I can confirm, the original pair has held up in the same condition as day one in terms of stretch and feel, with only some minor pilling on the seams that you only notice if you look carefully - even with a period of multiple washes a week for about 4 months before I caved and purchased more.
