The Glide-Lock system lets you add accessory pouches at whatever height you want along the sides and front of the bag.
Since the Vertex 200 AW is meant to carry a lot of gear, it makes sense that it has a hardcore harness system. The harness has eight adjustment points, ergonomically contoured shoulder straps, a well-padded waistbelt, and a chest strap that stretches, so it can expand and contract with your chest as you breathe. Once you have the harness system properly adjusted, the Vertex 200 AW lets you carry lots of gear very comfortably. Plus, if you need room for one or two more lenses, you can always add a pouch or two.
The Vertex 200 AW's harness system is as advanced as you can find on a camera backpack.
Lowepro's Vertex 200 AW has a lot going for it. If it has one major flaw, it's probably just that it's more camera bag than a lot of people need. Also, some people might complain that there are no wheels, since the bag can become quite heavy when it's fully loaded with gear. If you're looking for something slightly smaller, you should check out Lowepro's Vertex 100 AW, which is nearly identical, but smaller than the 200 AW. Similarly, if you need a bigger bag, the company's Vertex 300 AW offers even more carrying capacity.
