Dynamic duo: heat and cold in one great package.

Cold therapy works by constricting blood vessels, resulting in a decrease in blood flow to the area of application. This helps to decrease swelling and promote healing. Heat therapy increases blood flow to the area to help relax muscles and decrease pain. Put them together and you've got a lot of natural healing at your disposal for relieving sprains, strains, tendinitis and other injuries, as well as stiffness and poor circulation. This pain management system is even more dynamic.

Relief from strains, sprains, tendonitis and other injuries. Unique strapping system securely fastens anywhere on these hot and cold packs. Non-toxic gel is biodegradable and retains therapeutic temperatures longer. Soft, plush "frost-free" cover protects your skin. Store in the freezer; stays soft and pliable. Heat in microwave.
