Thank you for viewing. Purchased about 7 years ago, worn several times. These are jogger pants with pockets made of DRY material, suitable for spring and summer. They have a mesh-like texture, so sweat dries quickly. I think you can wear them comfortably year-round for indoor exercise like at the gym. I didn't find any noticeable stains, but there's a possibility I missed something. Please refrain from purchasing if you are concerned about minor details. No returns accepted. Color: Gray系 (Gray-ish) Stains, tears, odors, etc.: None
