These are Under Armour leggings designed to keep your body and skin cool. They are new with tags, but have been stored at home. As shown in photo 11, there is a very faint, almost invisible mark that looks like a thin line. I think the pants are see-through, so I believe they are designed to keep you cool. They would also be good under short shorts or skinny pants. Please note that these have been stored at home, so I apologize to those seeking a perfect item. Thank you for your interest.
