Francisco S.wrote a review of The North Face Mentor Backpack - 2150cu in on September 22, 2008
This backpack is much larger than i expected, it has a sleek look, and many pockets. its main pocket is large enough for about two to three days of clothing, or a laptop and two large textbooks(although i held three i had no laptop in it). The water bottle holder is fine if you don't mind leaving it unzipped for larger bottles(from 16 oz. bottles and up, can't fit gatorade bottles in it, at least i never tried), the smaller ones fit jut fine into the pocket.
