The S10 “Arm-Adillo” Shoulder Stabilizer was created for patients needing comfortable shoulder stabilization following an injury or surgical procedure. The two 1”x3” hook and loop straps originating from the bicep attach to body of brace for support and it is made of a durable foam with binded edges that makes it extremely durable. This is a redesigned version of the original S5. The S10 is not only more durable but also features a more versatile abduction control and has more sizing versatility. It is vailable to fit either the right or left shoulder. Measurements are taken around the check, just below the arm puts. With this product, it is better to go up a size if the chest measurements are close to the upper end on the sizing chart.
