The 85cm support strap can be adjusted to hold the gel pack to various parts of the body. It is designed to be used for hot and cold applications as well as for compression with the use of the support strap. Use to treat muscle pain, swelling, bruising or joint pain and promote healing. The included support strap attaches to the hot cold pack using Velcro, allowing the hot/cold pack to be secured to the body without having to hold it in place. ThermX hot cold packs are designed to be flexible even when frozen and made with the highest quality components to ensure they do not leak. The included support strap can be used independently of the gel pack and includes a starter loop for attaching to your arm or foot. The ThermX Hot/Cold reusable ice/heating gel pack is designed to naturally relieve pain by using either hot or cold therapy, without the use of medications. Heat therapy is an effective treatment for pain associated with muscle spasms, muscle injuries, sport injuries and insufficient or poor blood circulation, as it relaxes injured muscles. Cold therapy is effective for the treatment of inflamed swollen tissue and muscles, reducing blood flow and bleeding, and helping to prevent swelling and inflammation.
