The hot/cold pack can be heated or cooled as required. Cold treatment started immediately after an accident relieves pain and swelling in most sprains, falls, bruces and other bumps. Heat treatment relaxes muscles, affecting, for example, neck pain, stomach ache and many other ailments. An excellent tool for all athletes.
Comes with a handy strap to keep the pack in place at the desired spot, such as around the knee or ankle. Do not place it directly on the open wound.
