    • much larger than I expected

      This backpack is much larger than I thought it would be from the pictures. It has a strap that goes around your waist that I did not realize was on it. I did not like the way the strap looked or felt. Color was nice and it looked like the bag was good quality, but I disliked the strap so much that I returned it.
