These are black Uniqlo leggings. They are regular leggings, not Heattech. Both pairs show signs of wear, such as fading on the elastic waistband and slight thinning at the knees. One bonus pair has a snag that looks like it might become a hole in the right knee, but could still be used as an inner layer, etc. Please comment if you don't need them. Only those who understand the condition, please. Thank you for looking.
