The Elasto-Gel Multi-Purpose wraps are the most versatile hot and cold therapy options for a family or an individual who wants to use them on multiple areas of the body. The 6"x30" is an ideal size in that it can be used on the back, abdomen, shoulders, neck, knee, thigh, and head. We strongly suggest that users store the Elasto-Gel in the freezer so it is available to treat an acute injury with cold therapy. It can be microwaved for 45 seconds and then used to treat chronic or arthritic pain as needed. All Elasto-Gel products are proudly made in the USA.
