Elasto-Gel Hot/Cold Knee Wrap with Patella Hole. Made utilizing a tough, flexible, high-glycerin gel that is covered with a four-way stretch material that allows maximum conformity, hot and cold transfer, and comfort. Remains flexible, even at a -20 F. Microwaveable. Will not leak if punctured. Will not dry out. Durable, comfortable and easy to use. Latex-free. Knee Wrap with Patella Hole, Large/X-Large
It is easy to use and easy to store. My concern is it is not as cold as other options I have tried.
