Caldera Products delivers comfortable, deep-penetrating cold or hot therapy to injured joints, ligaments, and muscles. These may be easily used for either hot or cold therapy. When heated the products provide heat therapy to the affected area and when used cold, products provide soothing cold without causing trauma to the skin and nerves. Note that you never apply gel packs directly to the skin. The products are designed with adjustable straps and conform to all contoured areas of the body allowing for complete flexibility with your every movement. All therapy wraps include a compression strap with reusable heat and ice packs for customizable treatment for pain and swelling. From neck wraps, therapy wraps, to gel packs with cover, we can serve you with anything to treat pain and injuries almost anywhere on the body. The proprietary formula will stay flexible and comfortable right out of the freezer or microwave. Moreover, the adjustable straps and design make the application easy to use.
