I was a little concerned when I took this bag out of the box because it looked on the small side, but I was pleasantly surprised to see how much of my gear it can hold. The compartments are very flexible and you basically build it yourself with the set of cushioned dividers they provide. Even the flap that separates the top and bottom compartments is held in place with velcro so you can remove it if you want one large compartment. The dividers are strong and well cushioned and the velcro holds them firmly in place, in fact I had to struggle with a couple of them that adhered too soon.I love the look and feel of canvas backpacks and this one did not disappoint. The shoulder straps are well cushioned and feel strong enough to take the load. The top flap closure is unique using a hasp that has three hooks which provides flexibility in the amount of gear you can hold in the top compartment. That would be ideal to throw in an extra shirt or jacket when I'm out on a shoot. I'm not a huge fan of the clasp but maybe it will grow on me.There are slots on the sides for a water bottle and tripod, and one compartment on the bottom half that closes with magnetic clasps. I would have preferred one or two other compartments to hold smaller items, but overall I'm very happy with this camera backpack and I can heartily recommend it to you.
