Abstract: An arm sling comprises a sling pouch in which a retaining strap or belt is secured to a back panel of the sling pouch intermediate the ends of the sling pouch. The restraining strap is secured to the back panel intermediate the ends of the restraining strap and preferably at two points or along two sets of stitches. Opposite ends of the restraining strap are removably securable together by a fastener such that the restraining strap may be readily secured around the torso of the wearer with the sling pouch and the arm therein being held against the wearer's abdomen without pulling on the ends of the sling pouch. The restraining strap is preferably secured to the back panel at a slight angle, approximately five degrees, relative to a bottom edge thereof and from a wrist end to an elbow end of the sling pouch to support the wrist in a slightly elevated orientation relative to the elbow when the sling is donned.
