These are Ion's Nobirucchi pants. They were never worn and the size was outgrown. They look like a pair of chinos. They seem to have a sleek fit and a beautiful silhouette. The lining is lightly brushed, so I don't think they'll be too hot. They contain 3% polyurethane and are described as having horizontal stretch. The waist is not elastic, but has a zipper and button closure. There are four pockets, two in the front and two in the back. The overall photo appears white, but the actual color is closest to the third photo. Original price: 2508 yen Brushed lining
