Uniqlo Boa Sweatpants 150cm These are Uniqlo sweatpants in size 150, long gray pants made of soft polyester. Thank you for viewing. These are warm boa sweatpants. I tried them on and stored them at home, but they've become too small. There are no noticeable stains. For those who understand that these are used items, thank you. I will compress them for packaging when shipping.
