Southwest Technologies Inc. is the manufacturer of Elasto-Gel™ therapy products. Our line consists of over 40 different shapes and sizes so we can best fit each person's special need. Elasto-Gel™ products may be used for either hot or cold therapy and will not leak if punctured. When heated, products provide moist therapy heat and when used cold, products provide soothing cold without causing trauma to the skin or nerves. In addition, when used cold, the products remain soft and flexible even at -20ºF. The products will not dry out, become hard or change form and are re-usable. The products have the ability to conform to all contoured areas and move with patient movement. Products are covered with a four-way stretch material that allows maximum conformity, heat transfer and comfort.
