Uniqlo Heattech denim pants, size 120. The color is black. They are denim and made of thick fabric, not brushed on the inside. They seem stretchy and easy to move in. I purchased these here, but my child didn't wear them because the color was too plain. There is some slight fuzzing and fading of the fabric, but I think they are still clothes that can be worn. Please understand that these are used items and have been stored at home. Color: Black系 (Black) Pattern/Design: 無地 (Solid) Pant Length: フルレングス (Full Length)
