I adore this bag. It looks great, it has loads of room, plenty of compartments and it is very sturdy.
I have been using it for over half a year now, and it still looks as good as new. I especially like the zips, as they are very tough and look like they can take a beating. The straps are wide and very comfortable and as the bag is rather thin the weight sits close to your back, so that you don't feel like you are going to fall over any second. The only thing I miss on this bag is a strap to go around your waste.
I bought an Eastpak, as I had a previous model and that lasted me through 3 years of university. Now it is in use as a bag for muddy outdoor sports and just doesn't break. These things are tough!
