So, you have your urban gear backpacked and off you go on foot or public transportation. What if you must go inside premises where you will be separated from your kit (for example, it will be stowed in a locker) and your concealed handgun can’t accompany you? Check out the GunVault MicroVault with Oakley Panel Pack.
You might even be able to deploy the wire cable lanyard that accompanies some lock boxes. The above box has one.
