Yes, it is normal to have a little bagginess around the shoulder as this slack allows for full range of motion without restriction.

Please refer to fitting instruction video for a visual demonstration on how to make slight shifting adjustments to accommodate different ranges of shoulder support.

No, the K2 sleeve does not have to be secured exactly at the wrist for it to work properly. The sleeve will still function as intended as long as the elbow polymers are overlaying the medial side of the elbow.

Kinetic Arm Returns

The Kinetic Arm sleeve is designed to meet most regulations and has been worn under uniform in game. However, rules are at discretion in different leagues in different sports.

With regards to baseball and softball, 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.

Materials:

K2 BioKinetic® Adult Sleeve - Nylon, Poly-Spandex blends.

K2 BioKinetic® Youth Sleeve - Nylon & Spandex blends.

Whether or not to wear a shirt underneath the Kinetic Arm is largely a matter of personal preference.

It is advisable to try wearing the Kinetic Arm with and without a shirt during training or practice to determine which options feel more comfortable and allow you to perform your best. 

Some individuals find wearing a fitted shirt or base layer underneath adds an extra layer of comfort to help prevent any potential irritation or rubbing against the skin. If you have sensitive skin or are prone to chafing, wearing a fitted shirt underneath may provide an additional barrier and enhance overall comfort.

The Kinetic Arm base layer is available on our online stores, which has an ergonomic design to help keep seams off high abrasion areas, increasing durability and comfort, along with thumb access holes to help keep base layer in place while putting on Kinetic Arm or making adjustments. 

The Kinetic Arm effectively reduces arm stress by offering dynamic support and stabilization to the elbow and shoulder during athletic or repetitive movements. Its revolutionary, multi-patented MuscleWeb® design provides targeted support to the joints during high-stress vulnerable ranges, all while allowing for a full range of motion.

Wearing this external arm support system has been scientifically proven to offload dynamic arm stress by providing multi-directional elbow and shoulder support during repetitive arm actions.

This is why Kinetic Arm has been regarded by customers as the best shoulder brace and best elbow brace for dynamic arm motions in activities and sports such as baseball, softball, volleyball, football, tennis, pickleball, and javelin.

The Kinetic Arm features a multi-patented MuscleWeb® design that mimics natural anatomical functions, providing reinforcement to muscles, ligaments, and joints for safer motion and reduced arm stress. This innovative technology uses strategically placed polymers to deliver targeted, multi-directional support to the elbow and shoulder, stabilizing joints during dynamic movements. The flexible web design offers activated support in vulnerable positions, offloading strain from critical areas while promoting optimal movement mechanics. This external reinforcement minimizes the risk of fatigue, pain, and overuse injuries, allowing athletes to maintain full range of motion and alleviate stress during repetitive arm actions.

The Kinetic Arm can help optimize mechanics by promoting safer anatomical ranges of motions, helping to improve joint alignment and stabilization to help improve mechanics and offload dynamic arm stress.

It works because it has an embedded MuscleWeb® design that gives a web of support to the elbow and shoulder to help reinforce the arm and efficient movement patterns without restriction.

With regards to overhand the throwing, these repetitive arm motions can cause fatigue to where the arm will have a tendency to lag behind as the body rotates which can cause excess stress on the elbow and impingement at the shoulder, and more stress on the labrum.

The Kinetic Arm overlays the elbow and shoulder to help reinforce and stabilize the arm to help improve mechanics and maintain safer ranges of motions.

No. The Kinetic Arm brace does not restrict motion or change delivery.

(If any restriction in range of motion is felt, simply shift the chest part of the sleeve an inch or two towards the dominant arm or loosen the strap).

This combined elbow shoulder brace is designed to allow full range of motion without restriction. Engineered with flexibility in mind, this dynamic sleeve is designed to synchronize with various arm actions.

Yes. The Kinetic Arm is backed by data and published research. Available on How it Works page on website.

No. Wearing the Kinetic Arm will not cause reliance or dependency.

Athletes are still be able to build strength and the necessary physical adaptations, because they still have to use their muscles to generate that force for that movement. In other words, the Kinetic Arm does not assist to move your arm for you.

There have been no signs or reports of muscle atrophy with long term use, because of the force generated that is required to move the arm during arm motions such as throwing, swinging, serving and hitting.

Peak stress happens in passive ranges during dynamic arm movements.

The Kinetic Arm is designed to give activated support to the elbow and shoulder in these ranges to help dampen arm stress.

If you are at all concerned about dependence or reliance, just use it on and off as a workload management tool especially on heavier workload or recovery days.

The Kinetic Arm can be worn during training sessions, games, and practice to help manage arm stress and prevent injuries. For optimal results, consider wearing the sleeve during both high-intensity activities and recovery sessions.

Many athletes find it beneficial to use the Kinetic Arm as part of their routine, helping them maintain performance while minimizing fatigue and risk of overuse injuries.

Ultimately, the frequency of use may depend on individual needs and comfort. For personalized recommendations, it's best to consult with a coach or a sports health professional who understands your specific activity level and goals.

No. The Kinetic Arm is not a performance enhancer, it is a protective device designed for the shoulder and elbow to help reduce dynamic arm stress.

The Kinetic Arm does not influence skill, change delivery, technique, strength, conditioning, or overall training.

This stress reduction sleeve, helps to safeguard the arm to help aid in arm overuse injury prevention.

Wearing the Kinetic Arm promotes safer anatomical movement by encouraging cleaner arm mechanics and reducing stress during critical phases of dynamic movements like throwing, swinging, serving, and hitting. It provides activated support when stress is at its peak in vulnerable passive ranges, helping to protect the arm from strain and overuse.

Because the Kinetic Arm helps to optimize mechanics and reduce arm stress it allows athletes to build strength and get more reps in with less fatigue and strain on their arm, so they can have a safer approach in gaining and sustaining velocity.

Athletes that have worn the Kinetic Arm have claimed it has helped them gain and sustain velocity over time, because they were able to train with higher intensity and safer progressions, because they have less arm stress and fatigue.

The Kinetic Arm stands apart from traditional arm braces or sleeves due to its innovative, multi-patented MuscleWeb® technology. While traditional braces or sleeves typically support only one joint (either the elbow or shoulder) and often restrict movement, the Kinetic Arm provides dynamic, multi-directional support to both the elbow and shoulder simultaneously, without limiting range of motion. This external web of support helps optimize mechanics, reduces arm stress, and minimizes the risk of fatigue, pain, and injury. It's the only arm support scientifically proven to offload dynamic arm stress while allowing athletes and active individuals to perform at their best.

Yes, the Kinetic Arm can be worn while training, to help offload stress during training exercises for added protection and support.
