I bought multiple pairs of these for my 13-year-old as well as myself. We both wear the same size and these are really true to size. What I love the most about these is how heavy the material is. These are not light weight like other joggers that we have bought in the past. I do agree with a lot of the reviews that they pill after washing, it’s not a huge deal to me. I have found that if you wash on cold and then hang dry, they don’t pill as much. But I bought a fabric shaver, and that solves the problem. I also bought my husband a couple pairs three years ago and he still wears them and we have had zero issues with them other than the pilling.
