Amazing bag!!!! I looked for months on end to find the right bag for backpacking, but without having to carry it around if there's good terrain or without having difficulty finding things which is perfect with the suitcase style opening (also amazing to pack)! I also have a difficult time with packing light so the bigger the better and this was the biggest I found in a backpack. I literally cannot fault this bag! It has so far been to Africa with me, and it's soon to go around Europe, Asia and Australia and I'm confident it will withstand the elements. It's extremely well made, I love how the backpack straps (which includes a padded hip strap) can be zipped away so you can use it as a suitcase and also so the straps don't get trapped on conveyor belts at airports, there's enough pockets to put the little things in with plenty of room which also saves valuable space! Well worth the money!! I love this bag! Couldn't believe I found one with everything on my tick list!
