We bought this bag for an upcoming trip overseas. We however did a test run withit over the holidays and it is a fantastic bag. THe material is extreamly duable and it has many compartments. You can unzipper the side to make the bag larger, giving you more space. The biggest selling feature was the backpack straps. When you take the straps out their is even a piece of material that covers the sheels so if the wheels are dirty it does not mess up your cloths. I am very happy with this product and we are considering buying another one.
