Polar Ice Warm or Cold Compression Pack

The Polar Ice Warm or Cold Compression pack can be used for cold or warm compresses. Once frozen, this cold ice pack can be used for extended periods of time without losing its temperature. Ice crystals form within the pack while it is in the freezer, which in turn improves the deep tissue chilling effectiveness throughout its application to the body. Even when frozen, this versatile and flexible ice pack can still contour to your body and muscle curvatures. Heat in water or water-covered in the microwave, and the same versatility and flexibility is maintained in an effective heat compress.
