These are Uniqlo Kids' half pants (shorts). Made of 100% polyester, they have a smooth feel, so I think they are suitable for sports, leisure activities, or loungewear. I wore them for one season. There are no noticeable scratches, stains, or stretched-out elastic, but as shown in the images, there is some pilling on the edges of the inner fabric. I may end the listing suddenly. I plan to ship via Yu-Packet Post Mini. I will fold them up small, so please be aware of this.
