This wrap is getting rave reviews from our testers...the double width of hot or cold packs covers more of your back to help relieve aches and pains. Beautifully constructed. Just the thing for warm up before a workout, recovery after, or any time nagging back pain or muscle tension leaves you craving a dose of ice or heat. We love having it as an addition to our store! The extra thin profile allows you to wear it over or under clothes. Another great idea from our friends at Spand-Ice.
