The newly revised Radio Chest Pack features our all new Silent on Set system. The days of worrying about being too loud are over. Our all new silent auto opening closure system adds ease to all workers behind the scene. You will no longer need to worry about velcro being disruptive on set. This feature allows you to get in and out of your pouches without making a sound. All products featuring the Silent On Set closure will also feature an adjustable retention system. The user has full control over the slack or tension of the closure cord. This also allows the user to replace the cord in the event it loses elasticity.
