This versatile bag measures 9" wide x 11 " tall and 3.5" deep. It has 1 front pocket with a magnetic closure, 1 large inside pocket that you could fit a tablet in and two smaller inside pockets to fit things like a cellphone or car keys. The cool thing about the front pocket on this bag is because of the way it is made, it has a bonus "secret" pocket behind it that is covered by the main flap.
The crossbody or shoulder strap easily converts to a backpack without snapping unsnapping anything, just pull. I really don't know how it could be easier.
This bag is so versatile and has so many purposes for guys or girls, adults or children.
