- Brand: UNIQLO - Size: 110cm - Material: 90% cotton, 10% polyurethane - Design: Black and white checkered pattern Thank you for viewing. These are leggings from Uniqlo. They have been worn a fair amount, but there's not much pilling, and they are still perfectly wearable. How about using them for situations where they might get dirty, like at nursery school or playing in the park? These are items stored at home. Please understand. Thank you.
