This bag was given to my son when he started college. It’s in like new condition,he never used it but was “thrown” in his closet. The metal Prestige label still has its plastic on it. The bag measures approx 20” wide and 15” tall. The inside is approx 13”. There is a grey strap that came with the bag that I will include though it looks different than the strapping. This is a very nice bag that will fit a lap top and other stuff too.
