Abstract: A sling system for providing both reliable immobilization and comfort is disclosed. The sling system comprises a lightweight elastic sling, a support wedge, and a restraint band for securing the user's hand and/or arm to the support wedge, while at the same time the user's shoulder and arm are supported in the sling. The sling comprises various pleats and darts, such as the shoulder compression pleats, that allow the sling to be form-fitted snuggly and comfortably in cocoon-like fashion around the shoulder, arm, and elbow of the user, thereby securely and comfortably immobilizing the injured or repaired shoulder and/or arm and redistributing the weight of the arm away from the shoulder alone, which may be injured, to the combination of both the shoulder and the torso.
