This is the best camera bag, I've owned. I travel for work as a photographer and used a popular roller bag in the past, but I travel on smaller planes which forced me to check the bag at the gate, which I never want to do. I like to have my gear with me at all times, so this backpack is perfect as I can carry it on and it keeps my gear safe.On top of the size and ease with traveling, the design of the bag itself is exactly what I've been looking for. It's packs efficiently, doesn't waste any space, and each compartment is useful and well designed.The gear I carry when traveling + additional travel things:- Full frame body- flash- 4 lenses (50mm, 35mm, 24-70mm, 70-200mm)- charger, batteries- laptop- kindle (for the plane)- carry on toiletries- change of clothes- snacks- water bottleThis bag is truly the best one I've used. I highly recommend it!
