Keeps the heat in
I was surprised how long it stays warm, works really well!
I've had heat packs in the past and wouldn't use them long as they were too hard to keep on. This is perfect as it attaches to your body and you can move around with it on.
I've looked for this product for a while. I've bought heat packs in the past and wanted to be able to place it in the right spot and this heat belt is super easy to mould to the body and stays warm for a long time.
Really liked this helped with my back pain and was easy to use
