Thank you for viewing. This is a set of 4 warm, fleece-lined leggings. The size is M, but it fits M to L. The tag says it's a set of 5, but this is a set of 4. 3 are new, unused, and unopened. One was opened for photography and immediately put back in the bag. Please refrain from purchasing if you are sensitive to items that have been stored at home for a long time.
