These are 2-way stretch woven shorts with built-in inner shorts, made by ASICS for trail running. They can also be used for various other purposes such as regular marathons and jogging. Features multiple pockets, including a zippered pocket on the back. Worn once and professionally cleaned. The inner shorts were worn, so they were not worn directly against the skin. There are no noticeable defects. Color: Performance Black Size is S (overseas size). I felt they were a bit large for me, so I'm selling them. I am 169cm and 50kg. I think a Japanese M size would be a more appropriate fit. That's all. These are used and worn items, so please consider this a used item and only purchase if you understand this.
