The Gadsden Dynamics Ammo Bag is one of those useful items that you simply need to have when you head off to the range. These are made from a heavyweight mesh fabric that is extremely durable and breathable - if they get wet they dry rapidly so you don't have to worry about the contents being damp for long periods of time. All seams are reinforced with a heavy weight bonded nylon thread which makes these bags last a very long time under heavy use.
550 parachute cord and a cord grip close the top and also provide a way to carry the bag around. Two of these bags fit perfectly inside a 50 caliber can, which makes them great for separating different ammunition calibers in a single can.
