Query: Great backback, great quality.

I bought this backpack for college, as I needed a new one after I used the same old backpack for 4 years of high school. I was looking for one made of quality materials, lots of storage space, and adequate room to store a 15 1/2 inch laptop computer.This bag fits all my expectations and then some.The sheer volume of storage space is excellent; lots of nooks and crannies to store anything you want, and plenty of bag room to store at least 3 inch-and-a-half binders--with the laptop in the bag.The shoulder straps are very comfortable, and the material allows the bag to breath against your back. I have not had a problem with back sweat yet :)All in all, an excellent quality bag. A must for college.
