I bought this bag to try and simplify my commuting stuff.  I commute about 1 1/2 hours each way to work and I was carrying a purse and a bag for other stuff.  I wanted a back pack what was not to large but would hold my lunch a few folders and contents from my purse.  It holds it all and some!!!  I bag fits nice and secure to my back and there is plenty of room to grow a little.  The bag is put together very well and I have used it daily now for over a month and no issues.
