These are Under Armour mesh shorts. The size is YXL in the BOYS category, but due to the loose fit design, they are equivalent to a men's S size. They fit a 170cm, 60kg man perfectly. Regular men's sizes only had shorts with wider thigh and hem areas, so I purchased the largest size in the boys' category. However, the leg openings were still a bit loose, not what I was looking for, so they are being sold because they are no longer needed. They have only been tried on once, so they are considered new and unused. They were purchased for ¥2,750 from the official Under Armour online store. Please check the images for detailed measurements. The color is light blue. The first image is a reference image from the manufacturer, but the color in the other images is closest to the actual product. They are beautiful items that have only been tried on, but they have been stored at home for about two weeks. I would appreciate it if you understand this before purchasing. I am also selling them in a different color, navy.
