This is a great little pack. I can fit my SLR with a battery grip, 70-200mm lens, 2 smaller kit lenses, flash, chargers, and batteries inside the camera block. I will usually use the larger front pocket for extra memory cards and can also fit my 14in laptop in it with a little squeeze. The camera block just fits inside the pack and ads some rigidity to it so you don't have to worry about crushing everything inside. The main access to the pack is through the back panel, the entire back will fold out of the way so you have open access to it. I got the bomber color which doesn't look as white as it does in the picture, has a little bit of a green tan tint to it and the print on it makes it look really dirty. I have been very happy with the pack overall, just wish they have a couple more dividers to adjust the storage in the camera block.
