I kept debating on getting this for a couple of weeks. I'm so very glad I purchased this. I'm actually taking a trip that'll take me completely across the world! Carried a shoulder bag going there the last time. It was a complete nuisance - carry on + cross over purse - didn't make for a comfortable walk thru airports I wasn't familiar with and no time to spare. cross over purse kept falling to the front and not nearly as roomy. *light bulb time* - get something more comfortable, easier to handle. Checked reviews and colors. Saw this, fave colors, looked at the pics and VOILA -  Totally what I was looking for. I can even put 3 days worth of clothes in there, my makeup, pair of flip flops, a  hard cover book AND have room to spare (being a woman, I'm sure I can think of something to put in it lol). Not only do I LOVE the amount of room I have BUT on the top there are 2 zippers that touch and I can put a lock thru them (for security). I thought the smaller zipper on top was only for decoration but THAT'S EVEN ROOMY. let's not forget the vertical zippers that is an opening for storage, can we say ROOMY? I love it (could you figure that out by now?)
