Size: S Color: Gray (It's not as dark as the first image. It's closer to the seventh image, but a bit darker) The inside is fully fleece-lined and warm. These are old warm pants. They were very popular, from the era when they had zippers at the hems. These are used items, so there is some wear and tear, such as small pills as shown in the sixth image.
