Sounds like this is a great bag with enough room for books, notebooks, laptop, and a change of clothes (biking to school so that is a must). I'm sure it isn't waterproof but does it at least keep everything from getting soaked if I get caught in a downpour on the way to campus?
By the reviews I have read, it's pretty sturdy and handles spills well. Spraying it down with camp-dry or a similar fabric waterproofing spray will make sure your goods stay dry.
