The Chattanooga Sully AC Shoulder Support Brace is the most convenient and innovative acromioclavicular (AC) joint protector ever designed, allowing for full range of motion (ROM). The breathable, hook-sensitive neoprene vest grips the skin to allow precise placement of the donut-shaped foam pad. This hard shell foam pad helps to protect the AC joint from further injury. Specifically designed for comfort, there are no restrictive or uncomfortable straps. Universal fit allows the Chattanooga Sully AC Shoulder Support Brace to be worn on either the left or the right shoulder.
