The ActiveWrap Therapy Shoulder Wrap is a shoulder brace designed for positioning and controlling the shoulder girdle and trunk flexion or rotation. The wrap assists with muscle, joint, and tendon pain. Each wrap includes two latex-free, non-toxic, microwave- and freezer-safe hot/cold packs. The packs can be configured within each wrap in order to deliver either heat or cold to desired areas. These wraps are constructed of medical plush with Lycra trim for comfort and neo-Lycra for stretch and breathability. The packs stay soft during application while non-migrating gel maintains even pressure. SIZES: Small, medium (for chests under 40 inches), large, and extra- large (for chests 40 to 56 inches). The packs are 7 x 10 inches. COLOR: Black. WARRANTY: 1 year.
