These bags are very durable and serve many purposes.  Years ago I bought my first one when we were traveling.  There are lots of pockets so you can organize what you are carrying with you and find it easily.  The shape of the bag makes it quite easy to carry with no stress on your back even when it's packed to the limit.  I still have mine, but this year gave one to my daughter-in-law who now is traveling to her high school daughter's basketball games.  She can fit a small purse, her movie camera, her IPad, some snacks, a bottle of water, and everything she wants into one bag so that she doesn't have to worry about leaving something behind.  The small one would be great to use instead of a purse because of the way it's organized.  The large one is really large, so unless you need something almost for an overnight bag or really like to carry lots of stuff all the time, you wouldn't really need it.  They have several nice colors to choose from.  The microfiber fabric is an attractive fabric.  I also have one of the small leather ones for a regular bag.  It's a lot more pricey, but dressier.  I would definitely recommend any of the AmeriBag products.
