The Easyrig Vario 5 Strong with Large Cinema 3 Vest & 5" Extended Arm is a body-worn support system that is adjustable to support camera rigs weighing 30 to 55 lb. The system consists of the Vario 5 strong support bar, the large Cinema 3 double shoulder vest, and a 5" extended support arm. A carrying bag is also included for convenient storage and transport of the Easyrig system. The system works by using a suspension line to support the weight of the gimbal rig, taking the load off of your shoulder, neck, and arm muscles, and distributing it across your torso. The tension line is adjustable by turning a screw in the back, letting you dial in the appropriate amount of tension for your rig.
