I purchased this bag to replace a smaller one that I liked from REI when the Velcro wore out and I needed just a little more size to carry both a Blackberry and a Droid phone along with the essentials: driver's license, work ID, credit cards, keys, lipstick, and a comb.

This is the bag for you if you small bags and prefer to carry only the essentials in compact and compartmentalized unit.  I chose the black one and use it as my everyday purse, not just for travel.  I think it would fit nicely into a larger backpack and it easily accommodates a few other travel niceties such as a travel size toothbrush & toothpaste.  Personally, I like all the different compartments... a place for everything and everything in its place.  This is probably not the bag for someone who carries a lot of unnecessary stuff.

For those who prefer non-leather for animal rights or other reasons, this is an excellent choice!
