Uniqlo Ultra Stretch Dry Sweatpants 120cm The size didn't fit, so I've only worn them a few times. However, depending on how you look at it, there's a little pilling on the front of the thighs. Other than the above, they are clean, and the knees haven't stretched out. Made of sweat material with excellent stretch and dry function, so they are easy to move in and dry quickly, making them a useful piece of clothing. These are used items worn by a child, so please refrain from purchasing if you are concerned. #UniqloKids120
