This bag is the best backpack I have ever owned and has grown on me over the last few months of daily use. I use this bag as a backpack for college, it holds everything I need and best of all is easy to pack in a hurry when leaving class. When traveling the bag feels like a tardis, able to compact and keep taking more items. The multiple layers of water bottle holders are great and hold anything you need of any size. The packing system included works very well for trips. The structure is very comfortable and the materials hold up. The multiple storage areas are great including a extensive setup for pencils and pens and erasers on the right interior, a hidden panel on left interior, and 2 large segregated areas on front interior. There are 3 hidden storage spaces on the arms and on the back, there is a front pouch and a protected pouch between the locking mechanism. It is expensive, but if you will use it often it is worth it to have a item you can rely on.
