Very comfortable to wear.
I loved the SunnyBay Wearable Disposable Heat Patches.  Not only did the heat ease my back pain, the belt was very comfortable to wear.  First of all the belts fit me! :).  The belt was easy to adjust so the pads were covering the sore area.  I was able to put the heat pads exactly where the heat was needed.  Plus the pads stay warm longer than any others I've purchase.  I highly recommend this product for folks suffering with back pain.  I will definitely purchase this product again.
