Lightweight and breathable Mizuno training pants made of polyester. I bought these for sports, along with a windbreaker for winter, but I'm selling them now because I don't wear them anymore. I haven't worn them much, so I don't see any particular stains, but please forgive any oversight as they have been stored by a private individual. - Brand: Mizuno - Size: S - Material: 100% polyester (outer and inner lining) - Material: 85% nylon, 15% polyurethane (ventilation lining)
