Answer Hi! It does not have a traditional internal pocket. However, when the bag is out of its stuff sack (as pictured) the attached stuff sack can serve as as internal pocket of sorts. It is securely stitched to hang midway down one of the internal side seams and provides a 5" x 3.5" drawstring pouch. It easily holds credit cards and a lipstick when closed. I can put my iPhone 5 in it, but then the drawstring only partially closes.
Answer Yes, there is an interior pocket.
