picked up this bag after using the Vertex Gamut 2.0 for 4 months. After using this bag for 3 months I am going back to the Gamut2.0. The side pockets are not big enogh for most common 24-36oz water bottle. the main compartment is a decent size for the bag size. the smaller compartment has a trio of odd sized pockets, not quite big enough for standard business cards but not slim enogh for pens. the smaller exposed zipper is almost big enogh for phones of yesteryear, was not big enough for sunglasses like I thought it would be. even with the armor plate in the bag tend to tip forward when placed down on floor. does not have a small loop strap to clip keychain or hidden pocket to hold keys or fixed blade knife. shoulder straps are ok but tend to dig in after a couple hours wondering a local zoo. I went as far as to add a admin pouch into the smaller compartment just to keep things organized and in one place throughout the day of use. --- The Gamut 2.0 is a $200+ tactical bag with no ballistic protection. The commuter is a very basic urban travel backpack with a custom cut IIIA armor panel at $139. We can make you a panel for the Gamut though! Give us a call if you see our response Dave.
