I have many Baggallini bags and this is  my favorite. It is just the right size to carry a wallet along with a smaller tablet such as a Kindle or I-Pad mini. There are three pockets on the outside, which work well for cell phone and keys. Then there is a simple pocket on the back. Also, there are two zippered main compartments.

With this bag,  I have plenty of room for everything I need/want to carry without it being bulky and loosing items in the bag.
