These are Uniqlo Heattech Gear Pants. The inside is made of Heattech material, making them feel very warm in the winter. They are also suitable for outdoor wear. I purchased and wore these last winter season. There are no noticeable stains or scratches, and they appear to be in relatively good condition. - Color: Black - Features: Adjustable waist Size...L Color...Black系 (Black-based) Stains, tears, odors, etc...
