Using a tape measure to visualize how big this bag is does not do justice! This is my first Osprey bag, but you can be assured that it's not going to be the last. Fairly light at around 10lbs, be EXTREMELY aware that you are going to blow right by the 50lb limit for the airlines. This bag will hold it all, and wear like iron doing it. I will write an addendum after a near future 10000 mile trip!
