A cost-effective, high heat capacity thermal therapy device is described. The therapy device includes a plurality of discrete hydrophilic absorbers hydrated with a liquid containing a substantial amount of water. The water-retention mechanism of the discrete hydrophilic absorbers allows the water to freeze under normal freezer conditions (-20° F.), to 32° F., increasing the heat capacity of the therapy device. At the same time, the therapy device remains highly pliable when frozen as a result of reduced water flow out of the absorbers during the freezing process. The therapy device also remains highly pliable through repeated freezing/melting cycles because the discrete absorbers do not lose their discrete forms when thawed. |
