Calpak's backpacks have all the features students and adults need such as comfortable padded shoulder straps, pockets for your calculator, pens and pencils and more pockets for all the other stuff you carry. The Tracer is the perfect day bag. Fits most 16" laptops and features inline skate wheels, retractable handle system and multiple organizer pockets.
PROS: I am tall and I love that that handle extends high enough so I can walk comfortably. I am using it for work so there is plenty of room for papers. Rolls really smooth.
CONS: The laptop sleeve leaves a little to be desired. Its not a built in part but just an insert that flops around. I think it still protects the laptop fine, but wish it was a built in compartment. But other than That I am very pleased with the briefcase.
