Uniqlo Windproof Warm Easy Pants Color: Black The inside is fleece, and it's incredibly warm. I loved them because they were slim despite being warm, but the size no longer fits. The original drawstring is missing. I've worn them quite a bit, so there are some scuffs and pilling. There may be other overlooked imperfections. Please understand that these are used clothes. I have a cat at home. Please refrain from purchasing if you are concerned. Fleece-lined Warm Pants
