L.L. Bean: Maine Guide Rucksack
The body of this bag is constructed from a water-resistant waxed-cotton canvas, so it is made to last . . . perhaps even well beyond your school days. The leather straps and brass hardware add a touch of class to this rugged sack, however, so you may want to continue using it once you get your first gig. It will exude character, particularly after years of use.
