Kinetic Arm Base Layer

The Kinetic Arm K1 Brace is designed and recommended for athletes who play in high-intensity and or high-volume throwing sports.  Best option for workload management, recovery and rehabilitation throwing programs. This is because the K1 Brace has a multi-adjustable strap system to help customize fit and tension to assist in acceleration and deceleration control.

The K2 Sleeve is designed for people to wear in practice and game. Players of all levels who participate in throwing and swinging sports.

K2 Sleeve is designed for adult and youth players ages 6+. The youth sleeve is engineered to give a layer of arm protection to growing athletes to improve arm mechanics, consistency, while reducing arm stress that contributes to most arm overuse injuries.

* Athletes do alternate between using the K1 and K2.

Unlike traditional arm braces that are designed to immobilize or limit motion, the Kinetic Arm K1 Arm Brace gives full range arm support without restriction to help improve mechanics and offload arm stress while throwing and swinging.

The Kinetic Arm K2 Sleeve offers more than just compression because of its patented MuscleWeb™ design that has a strategic network of elastomers built-in to the sleeve to help reinforce joint stability in the shoulder and elbow which helps overall mechanics while reducing arm stress.

The Kinetic Arm works by stabilizing the shoulder and elbow to help optimize mechanics and offload arm stress while throwing and swinging. These dynamic arm stabilizers have an embedded patented MuscleWeb™ design, which is a strategic network of elastomers that overlay joints and give a web of external support to increase joint alignment and stability, to help improve mechanics and reduce arm stress, without restricting motion. The Kinetic Arm has been tested and proven to significantly reduce arm stress that is the leading cause of most arm overuse injuries.

The Kinetic Arm can help optimize throwing mechanics by promoting cleaner arm actions, and not letting your arm lag behind or go into vulnerable positions while throwing and swinging. It helps reinforce and support the shoulder and elbow when the arm is in weakest range.

During repeatable arm actions the arm can fatigue and start to lag behind as the body rotates which can cause stress on the elbow and impingement at the shoulder, and more stress on the labrum. The internal components are flexible and pull in the same direction as your muscles to reinforce efficient movement patterns. 

No. The Kinetic Arm does not restrict motion or change delivery. These dynamic sleeves are lightweight, flexible, and designed to synchronize with all arm actions. Every sleeve can be adjusted to customize fit and tension to support different arm care needs pertaining to the shoulder and or elbow. These dynamic arm stabilizers can be worn over or under uniform.  

(If any restriction in range of motion is felt, simply shift chest part to glove side or loosen the strap).

Rules are at discretion in different sports and leagues.

With regards to baseball there are no rules stating that you cannot wear a sleeve underneath uniform. As long as it is a solid color and is not distracting.

Little League Rule updated 2023 season

Rule 1.11a (3) Any part of the pitcher's undershirt or T-shirt exposed to view shall be of solid color. The pitcher's undershirt sleeves, if exposed, shall not be white or gray. Neoprene, if worn by a pitcher, must be covered by undershirt.

The Kinetic Arm K2 Sleeve is not a Neoprene sleeve.

K1 Brace - Polyester, Silicone, Spandex, Nylon, Polycarbonate, and TPR Neoprene seams.

K2 Adult Sleeve - Nylon, Polyester & Spandex

K2 Youth Sleeve - Nylon & Spandex.

No. The Kinetic Arm is a dynamic arm care tool that externally stabilizes the elbow and shoulder and offloads the most stress at the end range where peak stress is the highest and where the muscles are weakest. There have been no signs or reports of muscle atrophy with long term use, because of the force generated that is required to throw or swing.
