I have the 2008 version of this pack, seems a little different, but I will add my review. This pack is awesome. I use it as a day pack, it is probably on the bigger side for a day pack, but that just means you can bring more stuff :D. Durability is awesome, have used this pack year round for 3+ years and there is no sign of wear or tear. One thing I have to say is that, it isn't waterproof so make sure you don't put your cell phone on one of the outer pockets. Oh, and i gave up on using the camel back, too much fuss, i'll just stick to bottles.
