While it may be something that looks at home in Iraq or Afghanistan, and may even have a use or two here in the states, I highly doubt that it is all that useful given that it looks "military".
Looking "military" may be fine for a day in the woods, but it doesn't blend in well in downtown Chicago. Part of the idea, IMHO, is to blend into your surroundings and not be noticed. This buttbag only does that in a few locales that I think most of our readers would frequent on a significant basis.
Thank you for posting the link to your blog though, as it helps me to decide on a bag for woods use, which is very infrequent these days.
