I purchased this about two years ago shortly after returning to college. Since then, I used it daily for three semesters and continue to use it when I need it. The size I bought (not sure which, the 1428 maybe?) is the perfect size to carry two textbooks, or three if necessary. However, what I like most is that it looks almost brand new after two years of heavy use, and I'm not known to keep anything I own in mint condition. This bag is extremely durable and I would be surprised to find another bag that is so perfectly sized that would last anywhere near this long and still pay such a small price for it.
