A sleeve-like support member can be used to enhance the comfort and wearability of a convention sling. A conventional sling includes a pouch adapted for receiving a users arm to be immobilized. The sleeve-like support member is shaped to fit around a users shoulder, and further is adapted to attach to the sling pouch by one or more straps secured to and extending away from the pouch. An axillary strap can be secured to a bottom portion of the sleeve-like support member to secure the sleeve-like support member around a users upper arm. By securing to a users shoulder, the sleeve-like support member removes pressure ordinarily applied by conventional slings to a users neck, and provides an anchor point opposite the arm or shoulder to be immobilized.
