Embedded polymers overlay the front of the shoulder, providing essential supportive tension to stabilize the joint and reduce stress during passive ranges when strain is at its highest. This web of polymers helps to offload stress from the musculoskeletal system by preventing the arm from lagging behind as the trunk rotates during dynamic arm motions. By alleviating stress on the biceps tendon and labrum, this external layer of support helps protect the front of the shoulder, reducing the risk of common overuse injuries to the biceps tendon, labrum, and rotator cuff.

Built-in polymers strategically overlay the entire elbow, providing targeted support to the medial and lateral sides during dynamic arm movements. These external polymers help reinforce the joint, ligaments, and forearm muscles, offering essential stabilization, particularly to the medial elbow during external rotation and the late cocking phases of throwing, swinging, hitting, and serving. By externally stabilizing the elbow in passive ranges—where peak stress occurs—it helps reduce torque and dynamic stress, minimizing the risk of common overuse injuries such as medial epicondylitis, UCL injuries, and avulsion fractures.

Embedded polymers overlay the back of the shoulder, providing essential dual joint support and stabilization during force generation and arm deceleration. Acting as an active constraint, it minimizes joint stress by providing multi-directional support to the muscles and ligaments during dynamic arm movements. This polymer web design allows full range of motion while reinforcing the posterior shoulder to help offload stress by aiding in the eccentric control of the scapula and humerus, reducing distraction forces on the posterior shoulder and elbow, and delivering external support as muscles elongate.
