Great around town pack! I bought this pack to use as a light vacation pack for sight-seeing and light shopping as its smaller than the typical school backpack.
It has a nice separate fleece-lined pocket at the top of the pack perfect for sunglasses and my ipod. For volume reference, the main compartment will only fit one binder and one textbook, which means its perfect for sightseeing and souvenir shopping!
 
I use the elastic straps on the back to hold my sweatshirt so I don't waste cargo space. The shoulder straps are comfortable and the waist strap keeps it from bouncing around.
