The Physical Therapist's Hot/Cold Shoulder Wrap (Sm/Med)

Recommended by physical therapists, these wraps retain both heat and cold and transfer it to joints or muscles for superior therapeutic treatment for injuries or pain. Developed by Dr. Edward Stout, an expert in polymer chemistry, the body wraps are made of a tough, flexible high-glycerine gel that can be microwaved for heat therapy or chilled in the freezer for cold applications. The latex-free wraps are leakproof, even if punctured, and require no more preparation than a quick microwave or a brief time in the freezer (they won't freeze solid). The safe, non-toxic gel won't dry out or harden, and remains flexible even at -20º F. Wraps stay hot or cold for up to 40 minutes, move easily with you, and can be worn under clothing after physical therapy or strenuous exercise. Small/Medium Shoulder Wrap. Fits up to an 11" bicep. 17" L x 22" W (43/4 lbs.)
