KingPavonini Extra Large Ice Pack for Back Pain Relief with Extension Strap, 2 Pack Reusable Lower Back Gel Ice Pack Wrap for Lumbar Surgery, Sciatica, Herniated Disc, Coccyx Pain, Cold/Hot Therapy

This in my opinion is the best heat and cool back belt out there, and it has an extender which is great as it stays hotter and cooler for much longer. Going to buy another as this belt wont last long on Amazon well priced also.

Wonderful Product, great fit & such relief for my back, 2 ice packs great, can even wear belt around house, adjustable belt can fit everyone, it’s not to big at all..Love this product, highly recommend..

This ice belt is so comfortable and easy to use. It helps with my tailbone and up my spine without having to have multiple ice packs and I don’t have to lay down. Adjustable belt will work for average to extra large people. Once fitted to my waste it stays in place and doesn’t roll or move.

works and fits great

I bought this for my dog and it's perfect. She has problems in her column and hip and needs both hot and cold packs that cover the whole area. I couldn't find a comparable product for pets, so I went with the human one, it fits as though made for dogs! Since this comes with two packs I use one in the freezer and I heat the other one in hot water. Both packs seem very robust and so far I have no leakage. When frozen the icepack gets quite hard and a bit inflexible at first. The ice packs maintain their temperature for quite some time, way longer than I'd need it. They stay cold longer than they stay warm. I really notice a difference in my dogs behaviour when she receives the warm pack in the morning, so I guess the pain relief is working. The velcro still works perfectly after a few weeks of usage and the whole bandage stays put even while walking around, laying down or jumping up. Money well spent!
