The Road Runner(TM) is a casual running, concealment holster that can be worn under or over your garments. It is what we refer to as "hide in plain sight", and DeSantis invented the concept. The gun pocket can be accessed from either side making the Road Runner(TM) ambidextrous. It is lightweight and well padded on the body side. The outer pocket has room for keys, wallet, ammo or whatever you may need. . Like all DeSantis products, the Road Runner(TM) is made from very durable materials for a lifetime of use.
