Arm & shoulder immobilization - Keeps elbow at ~90°, restricts abduction, extension, internal/external rotation—protecting shoulders and clavicle after injury.
Adjustable straps - Shoulder strap with padded support plus a waist (swathe) strap provides firm, customizable stabilization and reduces neck strain.
Thumb loop and broad sling pouch - Ensures correct arm position, minimizes rotation, and allows finger movement during healing.
Universal fit & ambidextrous use - Often fits both left/right arms and multiple sizes—common sizing based on chest circumference (S–XXL).
Comfortable, breathable materials - Made from padded foam-foam laminate or cotton-elastic blends; latex-free, ventilated, washable.
Easy application - Hook-and-loop fasteners, O-rings, and chest strap allow simple one-hand fit and secure hold.
