I have a Canon 80D with 4 lenses, flash, batteries, and other small accessories. I have room to spare. Very pleased with this bag. The velcro holds well on the shelves and the parts don't slide around. Very well padded. Nice bag for the price. Very happy with my purchase.
The locking zipper allow excellent security on this backpack. It has a very roomy camera compartment and also a very rooming accessory or clothing compartment. The rain hood that comes with it makes it weather resistant. The materials are very durable and long-lasting. All of the straps and buckles were excellently made and will last a very long time that would appear.
Overall, this is a great camera bag. Sturdy, spacious, comfortable, and looks great. The only reason I dropped to 4 stars is due to the magnetic clasp. I'd have preferred a true buckle or something a little more secure. The drawstring on the top does compensate for that a little though. I would have liked the laptop sleeve to be maybe 1 or 2 inches bigger to give just a little more space.
