SOFTBALL PLAYERS
IMPRESSIVE SOLUTION
Softball players put constant stress on their arms with repetitive throwing and swinging, which can lead to strain and fatigue over time. The Kinetic Arm sleeve provides dynamic, unrestricted support, stabilizing the elbow and shoulder when stress is at its peak. Designed to reduce arm stress and optimize mechanics, it helps players train harder, recover faster, and compete at their best—all while protecting their most valuable asset: their arm.
The Kinetic Arm provides unrestricted dynamic stabilization for softball players, reinforcing the elbow and shoulder without limiting movement. Its multi-patented MuscleWeb® technology supports overhead throws, underhand pitching, and fastpitch motions by stabilizing the joints through every phase of movement. Unlike traditional arm braces or sleeves, it helps maintain proper mechanics while offloading stress from high-impact motions like throwing and pitching. By promoting joint alignment and reducing strain, the Kinetic Arm allows players to perform at their best with greater efficiency and confidence.


Softball players wear the Kinetic Arm in both practice and games to manage their workload, reduce arm strain, and maintain peak performance with less fatigue. In practice, it allows pitchers, catchers, and positional players to get more reps while minimizing excess stress, helping them build strength efficiently and recover faster. The Kinetic Arm K2 sleeve is game-legal, as it meets most sport regulations—being solid in color, non-distracting, and not made from neoprene—making it suitable for use on the field, mound, and in the batter's box. During games, it provides unrestricted support to both the elbow and shoulder, optimizing mechanics and reducing strain during throwing, swinging, and intense innings. Its slim profile ensures it fits easily under the uniform without restricting movement.

PROVIDES ESSENTIAL
Dual Joint Support
Dual joint support is essential for softball players because the shoulder and elbow work in tandem during dynamic movements like throwing and swinging. The Kinetic Arm offers simultaneous support to both joints, stabilizing them during high-stress phases to promote optimal mechanics and minimize strain on vulnerable areas. By reinforcing both the elbow and shoulder, it helps maintain proper alignment, allowing players to move more efficiently while reducing dynamic stress on the joints.
MuscleWeb® technology is a flexible, multi-patented design embedded in the Kinetic Arm, using K-Tech polymers to provide targeted support to the elbow and shoulder. Designed to move with the natural flow of the arm, it reinforces the joints, muscles, and ligaments during high-stress movements like throwing, pitching, and swinging. The polymers activate when the arm reaches vulnerable positions, providing supportive tension to stabilize the arm during these critical phases of motion. The system also features an adjustable, detachable chest strap for a customizable fit, ensuring optimal comfort and support for players of all ages.
DYNAMIC ARM SUPPORT

Front shoulder support
The Kinetic Arm features embedded polymers that overlay the front of the shoulder, delivering essential support to stabilize the joint and reduce stress during high-strain passive ranges. This innovative design helps prevent the arm from lagging behind as the trunk rotates during dynamic movements, offloading stress from the musculoskeletal system. By alleviating pressure on key areas like the biceps tendon and labrum, the Kinetic Arm provides crucial external support to protect the shoulder and reduce the risk of common overuse injuries, such as those to the biceps tendon, labrum, and rotator cuff.

FULL ELBOW SUPPORT
The Kinetic Arm features built-in polymers that strategically overlay the entire elbow, offering targeted support to both the medial and lateral sides during dynamic arm movements. These external polymers reinforce the joint, ligaments, and forearm muscles, providing essential stabilization, especially to the medial elbow during external rotation and the late cocking phases of throwing, swinging, hitting, and serving. By stabilizing the elbow in passive ranges—where stress is at its peak—this design helps reduce torque and dynamic strain, lowering the risk of overuse injuries such as medial epicondylitis, UCL injuries, and avulsion fractures.

BACK SHOULDER SUPPORT
Embedded polymers overlay the back of the shoulder, offering crucial dual-joint support and stabilization during both force generation and arm deceleration. Acting as an active constraint, this polymer web provides multi-directional support to muscles and ligaments during dynamic arm movements, reducing joint stress. Designed to allow a full range of motion, it reinforces the posterior shoulder by assisting in the eccentric control of the scapula and humerus. This helps offload stress, reduce distraction forces on the shoulder and elbow, and deliver external support as muscles elongate, ultimately enhancing overall arm stability.
The Kinetic Arm dynamic arm stabilizers are backed by 10 years of researching and testing, demonstrating their effectiveness in offloading dynamic arm stress. All studies have undergone scrutiny and have been validated by research and medical professionals.
