Thank you for viewing. This is a Nike fleece set. The seller purchased and used it, but is now selling it because the size became too small. I purchased it as a size M, but according to the tags, the top is equivalent to M and the bottom is equivalent to S. However, it fit perfectly when I, who am 170cm tall, wore it. Because it's a fleece material, there are some areas with white lint from dust, but I don't think it affects the use. However, please understand that this is a used item before purchasing.
