This is a pair of running shorts from THE NORTH FACE's FLIGHT SERIES. It's an early model of the Enduris Racing Shorts, which were originally sold under the name "Flyweight Racing Shorts." I purchased these at THE NORTH FACE FLIGHT TOKYO, the only running specialty shop of THE NORTH FACE, and they are a limited edition model with "FLIGHT TOKYO" printed on the back. Although they are a few years old, I only wore them for important running races, so I've worn them less than 20 times. There are no noticeable scuffs, and the condition is fine. They are size L, but I think they would also fit someone who wears size M.
