I had the original FlapJill and Osprey replaced it after it wore out. (Some students have too many books!) The new version is even better. There are many compartments to stay organised and all the zippers for them are high quality. The single buckle is easier to open. The shoulder straps are far more comfortable than any other backpack I've tried. I highly recommend Osprey to friends and family, and their guarantee makes it an easy choice.
