The Quest is an excellent camera bag. It has tons of room for all of my camera gear plus more. I would highly suggest it.
Design: This bag can hold one camera, a telephoto lens, plus three or four (depending on size) more lenses. There is a quick access opening to grab your camera out from the side. There is a laptop pouch, water bottle holder, hidden tripod straps, chest and abdomen straps, a partition up front on top big enough to put a jacket in, and many accessory pockets throughout. It's unbelievable how much stuff you can fit into this backpack, and it's still fairly lightweight even filled to the brim with equipment. It comes with a waterproof cover to put over the whole bag as well in case of rain.
Fit: It is not as comfortable on my back as my DLX Heli Pro. This bag is quite a big bulkier and box shaped. It does not conform to your back like the DLX does. It is more comfortable if you use the chest and abdomen straps though.
Durability: The backpack is made out of ripstop fabric. Hiking through the woods in no problem, branches have no punctured or ripped my bag. There is a lot of padding in the camera compartment, which is obviously a plus.
Overall, this is a fantastic camera bag that I would recommend to everyone for storing their equipment.
