A fitted garment that covers specific muscle areas in the back area of the body. It is a spandex/cotton material with strategically placed pockets sewn into specific areas of the material. Inside these pockets, high-density foam therapeutic balls are placed to facilitate in massaging specific muscles in the back area of the body.

The garment fits securely to the upper body, and is secured by closing fitted straps and plastic buckles in the front area of the body. Because the garment is secured on the body, the person wearing it can move freely and with the use of their own body, they can apply pressure to the muscles by leaning against an object that would allow the balls to put pressure on these specific muscles. This process releases tension from the muscle and increases blood flow and range of motion. Because there are ten (10) pockets in specific areas of the garment, the same muscles are always being massaged allowing better relief and healthy blood flow to these muscles. The garment allows for the user to choose if they would like to use all the therapeutic balls at the same time or use only a few to massage certain muscles at certain times. The balls are interchangeable, allowing for this flexibility in use. Only high-density foam balls are used in this product, the pockets are sized to hold them in place for a greater therapeutic effect.
