Jonathan M.wrote a review of Gravis Battery Backpack - 28L on April 8, 2011
This bag is easy on they eyes, but has tons of space. The main pocket has a lot of little pockets in it for storing electronics/smaller items, as well as a lined/insulated pocket for a phone. The laptop compartment is giant, and seems to be pretty well padded. The pockets on the sides for waterbottles have elastic in them, but no drawstrings to adjust with. This bag is perfect for around town or in and out of class.
