I love this backpack. I bought it for my first trip to Europe and it served as the perfect travel backpack. I had no problems bringing it onto the plane as a carry-on, with the detachable daypack as a personal item. The rear flap that covers the belt and shoulder straps is great when stowing away the backpack. I also appreciate the lockable zippers on both the main backpack and daypack, especially when I stayed at hostels that didn't provide lockers. While trucking my stuff between cities and on trains, I appreciated how light the pack felt, because the fit is just right. The belt sits right on my waist without sliding down or chafing my hips and the shoulder straps curve inwards towards the chest. Best of all is the detachable daypack, which allowed me to drop off the majority of my things at a hostel, and right away go exploring armed with my daypack. I also love the rainforest green color - its not too drab and not overly bright.
