Thanks for the replies everyone.

Stevez, I have a couple more specific questions about the bag if you have a minute. I had heard of the hidden compartment in my research of the bag online. Since it is for a concealed handgun, it seems like it would only make sense that this compartment is easily accessible with the backpack on. Where exactly is this compartment located? Is it in the lower-back area? Does it zip shut like the other compartments, or does it close by some other means?

Also, are any of the other compartments subdivided or do they include any sort of organization slots, like the little pencil holders you see in so many generic backpacks?

Thanks again everyone for the replies.
