DonJoy Sully® Shoulder Stabilizer | Saunders Shoulder Support Brace

The Sully® Shoulder Stabilizer by DonJoy / Saunders is a functional shoulder brace designed to provide adjustable stabilization while preserving useful movement. Unlike a conventional sling intended primarily to hold the arm still, the Sully uses a form-fitting neoprene body and repositionable elastic straps to help control specific directions of shoulder motion.

This makes the Sully especially useful when the objective is controlled range of motion rather than complete immobilization. The manufacturer identifies applications including anterior, posterior, inferior, and multidirectional shoulder instability, rotator-cuff deceleration, shoulder separations, and muscle strains.

The brace is available in X-Small through X-Large, fits either the left or right shoulder, and is commonly used in sports medicine, athletic training, rehabilitation, and clinician-directed post-injury or post-operative programs. DonJoy describes it as a functional stabilizer rather than a rigid immobilizer.

Why the Sully Shoulder Stabilizer Is Different

The Sully combines a close-fitting shoulder garment with an adaptable external strapping system. Its perforated neoprene conforms to the torso and upper arm, while hook-compatible straps can be positioned according to the direction of support required.

The system includes a bifurcated neoprene strap plus two additional 4-inch neoprene straps, allowing clinicians, athletic trainers, and users to configure support around the shoulder rather than relying on one fixed strap path.

Shoulder Conditions and Applications

The Sully is designed for situations in which external support and controlled motion are needed without automatically placing the arm into full rigid immobilization.

Manufacturer-listed applications include:

A shoulder brace does not determine when an injured or postoperative shoulder is ready for unrestricted activity. Follow the guidance of the treating physician, physical therapist, or athletic trainer regarding appropriate motion and return to sport.

Sully Shoulder Stabilizer Size Chart

For the best fit, measure the chest circumference and the biceps with the arm relaxed and not flexed.

Fit tip: when chest and biceps measurements point toward different sizes, do not select solely from chest circumference. Because the upper-arm sleeve is an important part of the stabilization system, confirm both measurements before ordering.

Left or Right Shoulder?

You do not need to choose a left- or right-specific version. The standard Sully Shoulder Stabilizer is designed for use on either shoulder.

This is useful for clinics, schools, and athletic-training programs because the same-size inventory can be used for either side.

Sully Shoulder Brace vs. Other Shoulder-Rehab Products

The Sully is frequently confused with slings, immobilizers, and exercise equipment, but these products have different jobs.

If your rehabilitation plan calls for controlled shoulder mobility exercises rather than wearable stabilization, see our Shoulder Pulleys and Range of Motion collection or the Overhead Pulley System for shoulder range-of-motion rehabilitation.

For cold therapy used separately from the brace, we also carry the Chattanooga ColPac reusable cold therapy pack. These products serve different purposes and should be used according to the treatment plan provided by the appropriate clinician.

How the Sully Is Applied

The basic fitting sequence begins by placing the involved arm into the sleeve and securing the upper-arm closure. The body section is then wrapped snugly around the torso. The external straps are positioned afterward according to the type and direction of support required.

Because strap placement changes depending on whether the goal involves anterior, posterior, inferior, or multidirectional stabilization, the initial setup is best performed according to the manufacturer's application instructions or with guidance from a clinician or athletic trainer. DonJoy publishes distinct configurations for the different instability patterns.

What Comes With the Sully Shoulder Stabilizer?

Each standard Sully Shoulder Support includes the primary shoulder support garment, a highly adaptable bifurcated neoprene strap, and two additional 4-inch neoprene straps.

The product is available in black.

Care and Cleaning

DonJoy recommends hand washing the brace in warm water with mild soap, rinsing thoroughly, and allowing it to air dry. Residual detergent should be removed completely because soap left in the material can contribute to irritation and premature material deterioration.

Who Should Consider the Sully?

The Sully is particularly suited to customers who need more directional stabilization than a simple compression sleeve but more functional movement than a rigid immobilizer permits.

It is frequently selected for athletic and rehabilitation environments because the strap arrangement can be customized for the particular shoulder-support objective rather than locking every user into the same configuration.

For customers whose main objective is restoring shoulder mobility rather than external stabilization, browse our shoulder range-of-motion equipment instead.

Product Identification

Frequently Asked Questions

Is the Sully Shoulder Stabilizer the same as a shoulder sling? No. A sling generally supports or immobilizes the arm. The Sully is a functional shoulder stabilizer designed to provide adjustable support while permitting controlled movement.

Can the Sully be worn on either shoulder? Yes. The standard brace is designed for either the left or right shoulder.

How do I choose the correct size? Measure both chest circumference and the biceps with the muscle relaxed. Compare both measurements with the size chart before ordering.

Does the Sully completely immobilize the shoulder? It is better characterized as a functional stabilizer. Its straps can be configured to assist or restrict selected movements rather than functioning solely as a rigid immobilizer.

Can athletes wear the Sully Shoulder Brace during sports? The manufacturer markets it for athletic applications and controlled functional activity. Whether it is appropriate for a particular sport, injury, or stage of rehabilitation should be determined by the athlete's physician or athletic trainer.

What sizes are available? X-Small, Small, Medium, Large, and X-Large.

What color is the Sully Shoulder Support? Black.

How should it be cleaned? Hand wash with mild soap and warm water, rinse thoroughly, and air dry.
