Hotshotz 10 Inch Round Reusable Heating Pad for Pain Relief - Microwaveable Heat Pack for Back, Shoulder & Muscle Pain - Perfect for Home, Office & Travel Use

The 10″ Round heat pack is our personal favorite. This is our longest lasting heat pack. It can last up to 6 hours when properly insulated. The round works great for cramps and sore muscles on any part of the body. You can put it on your car seat, take it the ball game for a stadium seat or snuggle up on the couch with it and place it in your bed at night for hours of soothing heat.
