Theses are single lined and 3.25 inseam. They have the contour line to show off that Boo-Tay!! 😂 I put an arrow in the one picture of the inside of the short. There is nothing wrong with them, that is the pattern from the outside coming through the other side. There is no stains or marks on these shorts. They are in used good condition. If you have any questions please feel free to ask!
