This is a pair of Warm Reserve pants from PLST. The size is XXS. The shape is straight, and the line is sleek, more so than wide pants. They made my legs look long. I'm selling them because they no longer fit. I usually wear an XS in PLST. I don't remember, but it seems I chose this size for these. There's a kind of sealing on the back of the center line. They show signs of wear, but I don't think there are any major stains, so I would appreciate it if you would consider them. PLST Straight Pants Fleece-lined
