*ANOTHER VOTE FOR THE OSPREY EXOS 58 HERE *
I've just walked the West Highland Way over 5 days carrying the Exos 58 and it performed flawlessly, YES the pack dug in to my butt at the start BUT that was no ones fault but my own as i never had it set up properly, once setup right the pain disappeared. Great light pack which carries alot of gear and performs just right !!!
