At first I was disappointed by the sturdy no-glam fabric of this bag, but now I wouldn't want any other. It has 3 zipper compartments (2 on the outside and 1 on the inside, plus an outside open pocket (great for gloves, plane tickets, map, tissues), plus a full zipper top and lots of internal pockets for cell phone, credit cards, etc. It also folds easily so I could stick it in my back pack and take it on a plane without adding an extra piece of hand luggage. The main compartment can hold a good size paperback book. The larger outside pocket holds my long double-size wallet. After using for a day or two, you'll find this bag is your personal assistant!
