A shoulder complex and upper arm injury reduction system having a torso fitting part, an upper arm wrap part, and at least one movement control strap constructed of non-stretchable material. The movement control straps are strategically anchored on the system to control posterior, anterior, and multidirectional movement of the upper arm wrap part relative to the torso fitting part. The straps are length adjustable to control the amount of movement of the upper arm wrap part relative to the torso fitting part, and prevent separation of the upper arm wrap part from the torso fitting part beyond the strap length. The system includes a control strap that extends from the shoulder capping region to a strap mounting location below or above the shoulder capping region. The strap is length adjustable to allow tension to be placed on the strap and to produce traction between the shoulder strapping region and the strap mounting location.
