The Kinetic Arm sleeve has helped me get ready for the season by throwing either off the mound or flat ground work. I feel no stress on my arm. It helps clean up your ar path where you have no hitches or any lag in the back of the arm and keeps your arm in the right position to be powerful when throwing a baseball.

My son has been complaining of arm pain pretty much every day he has practice or a game. He just started pitching this year and trying to build arm strength. He's been wearing this sleeve for one month now and has not complained one day about arm pain. He wears it in practice and games and I do not even have to remind him, he loves it and treats it as part of his uniform.

This sleeve is a must have for all throwing athletes. After throwing with it my arm still felt fresh and like I didn't even throw a bullpen. The longer you can keep your arm feeling good the better off you will be.

Kyle Farnsworth
Former MLB Pitcher

The feel is incredible! Almost like having nothing on. I will not throw BP again without it, and want my guys wearing it. The Kinetic Arm has been a great asset to our program. Game changer for recovery and injury prevention. I highly recommend.

Colby May
Head Baseball Coach

Stubled upon the Kinetic Arm when searching for sleeves for icing elbows. Read the comments on FB and watched the YouTube videos and decided to give it a shot. My son loves having it on. Even in hot Iowa summers where the base layer is required as ahe is a pitcher, it is worth it! Intent to purchase the next size as he grows.

Joshua Humphreys
Baseball Parent

I have coached baseball for 37 years, having been a head coach on every level college down to T-ball. In those 37 years, the Kinetic Arm is the single best training aid I have ever encountered. I have 3 sons playing baseball, and I purchased each a Kinetic Arm sleeve. The results have been incredible. So impressed I plan to purchase them for my daughters that play volleyball. The Kinetic Arm is a rare tool that can be used everyday in practice and games.

Jeff Slinkard
Baseball Coach & Parent

I actually loved wearing the Kinetic Arm K2 Sleeve. I think it provides adequate support without being restrictive. I didn't think I would be able to serve well with it on, but it felt great! I felt like I was able to hit a bunch of serves repetitively without any issues that I would typically run into with fatigue.

Hank Sartain
Competitive Tennis Player and Physical Therapist

The K2 Sleeve is easy to put on and is so useful. You can really feel the medial support in the elbow and how it is less stress when you put it on and throw.

Yasunobu Okugawa
Professional Pitcher, Yakult Swallows in Japan NPB

As a physician of a 16 year old pitcher I was fascinated by the biomechancis of this arm device that specifically protects the joints and tendons from breakdown. The Kinetic Arm provides a way to pitch at a young age while proactively preventing the need for Tommy John surgery, and other injuries as well. Try it once, and the sleeve will speak for itself. I can verify that it meets absolute medical and biomechanical standards. My son and I are happy to have found it.

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.
