I bought this pouch to carry my PSK (personal survival kit) for when I'm out hiking, etc. My PSK is 7" x 4" x 1-1/2" in a plastic pouch and easily slips inside the main compartment of this pouch with room leftover for even more gear. The belt loop on the back will accommodate a 2" belt. The material seems durable. My only concern is the latching system- on the old true military ammo pouches the latches were metal but on the pouch I purchased the latches are plastic. They do seem heavy duty and I've had no problems so far.
