I was a big fan of this backpack, until it rained and my expensive textbook was ruined. Two stars because it is a nice bag, but for $65 it should be water repellant. Will NOT buy again.
TWO YEARS LATER.... I have updated my original review from 2 stars to 5 and this is why... When I first bought the bag it I used it when it was raining and water went through the zipper and ruined a very expensive book. Since then I have used this bag consistently, and is my first choice of backpack, I just avoid wearing it when it rains. I am giving this bag five stars because it very durable. I even use it to carry groceries, and am amazed how much I can fit in there. I have also taken this bag with me whenever I travel and it is a great carry on bag for my laptop, camera, and plane snacks.
