Lower back pain or lumbar pain costs millions of lost work days each year. Pro Ice's cold therapy lumbar wrap can alleviate the pain from an acute injury or help prevent chronic injuries from repetitive stress. These injuries can occur on the job, during hobbies or sports. Pro Ice cold therapy delivers a consistent temperature, creating the ultimate cold therapy. Standard cold packs fail to provide compression like Pro Ice. Compression not only helps deliver the ice where it's needed, but also keeps the wrap securely in place. Pro Ice's cold therapy does not drip, so no more wet t-shirts, and it allows for mobility when icing. For those whose backs are taxed during a day's work, Pro Ice provides the ultimate in convenience; even ice on the drive home without creating a mess. Without the ice insert, the lumbar wrap can be used as a stand-alone support belt. The large-sized model (PI 720) is intended for individuals with a waist size of 34-46 inches. Two other sizes are available – the PI 700 for individuals with waists from 26-33 inches and the PI 740 for individuals with waists from 47-58 inches.
