ICE COLD THERAPY UNIT: Fill the unit with cold water and ice - water is quietly circulated through the leak-free 52" hose to the pad, giving that specific area complete cold coverage. The cryo-cool system circulates cold water for up to 5 hours, continuously supplying cold to the area that needs it the most. UNIVERSAL WRAP TO RELIEVE WHAT AILS YOU: You may have any number of areas sorely in need of some relief and the universal wrap can take care of them. The universal wrap is 11"x 11" and includes a 3"x39" Velcro strap for use with a variety of areas like the hip, ankle, wrist, shoulder, leg, or elbow. Additional pad designs are sold separately. HELP FOR INJURIES, PAIN, SORENESS, AND SWELLING: Whether you're a sports hero, lead an active lifestyle, or just had an unfortunate misshape, injuries are a part of life. Cold water therapy can help get you through this tough time by helping to manage your pain and reduce discomfort or edema caused by traumatic injuries or post-operative pain.
