My mother purchased this Deluxe version of the Classic Book Pack for me my junior year of high school (1996).  Here I am traveling the state of Florida nearly 14 years later with the same bag in tow.  It has not once torn, worn or ripped. 

I would get another one, but I don't need to.  This one works just fine!

Amazing. 

Buy it. 

This thing is going to last until I'm 90...or dead.  Whichever comes first.
