Bottom of bag measures 27” and both end pockets zip out from there making this bag over 3’ when fill 16-17” high and 15+ inches wide. This is a great bag for any student needing to carry around their sporting equipment. Whether they play football, field hockey, lacrosse, tennis or the catcher on their baseball or softball team this bag is large enough to hold all their gear. Used but in very good condition, all zippers and straps functioning. Has been washed. There is a small zip up pocket inside I didn’t see before washing that had a term paper inside it. You may notice small paper flakes in that pocket (we’ll never know what grade he got on that assignment now)
