Excerpt: First, let me say this is a BIG bag. That’s not to say it’s a bad thing, but you won’t go sneaking around unnoticed with this on your back. The flipside (geddit?) is that you can fit in a huge amount of equipment and carry it comfortably all day.
Pros: Great bag for carrying big pro SLR gear for sports / wildlife shooters, Secure main compartment protects camera gear from opportunists, Very comfortable harness, All-weather cover, Clever hideaway tripod carrying system
Cons: Have to take bag off or swing it round to the front to get access to gear, Pocket on back of pack not lockable
