I have the extra small Ameribag and I was looking for something a little smaller. I am able to fit a change purse, wallet, cell phone, pocket calendar, and small reading glasses in the main compartment. It also has a zipper pocket and velcro pocket on the outside. This size is the perfect everyday purse for me with enough room for the essentials and a little extra room if I need it. I can always switch to the other purse if I need something a little larger for travel or special trip.
