Just Finished a 10 month round-the-world trip in March with this bag on my back. Looked at every bag I could find before I selected this one. It had the right balance of comfortable to wear on long walks, easy to access main compartment, and the matching backpack (I wasn't sure about) was the surprise MVP. The bag has plenty of room, and great utility with the wide opening front. I had a mountaineering bag that I almost used instead to save cash, but glad I opted to go with this because of the much easier access. Probably the coolest part is the small backpack that comes with it. As a traveler, you need your big bag of stuff, but a small bag for day hikes and sightseeing. Being able to clip this small bag on to the shoulder harness and keep it in front of you is great for balancing the load, and keeping your valuables safe. We only lost a laptop and a total of 4 cameras - but that wasn't the bag's fault. (The thieves know the good stuff is in the small bag) My girlfriend and traveling partner got the smaller 70L version and loved hers as well. Oh, we also saved on bag storage fees by being able to zip the small bag onto the big bag - there you go - one bag. Highly recommend it, and I'm buying one for my father who is retiring this week.
