Kidney Belt

KoolBak kidney belts greatly relieve back pain without slipping or rolling. The belts are made from a patented design consisting of multiple layers of breathable, coated, reinforced mesh with compression technology. They are strong, cool, washable, durable, and comfortable.

KookBak belts increase muscle activation–as measured by electromyography (EMG)–while standing and bending. This improves muscle tone and reduces fatigue.

KoolBak belts and accessories are handmade in the USA. We only use top-grade USA materials including a welded steel ring and Velcro Ultra-Mate (picks up 90% less lint than standard Velcro and is more durable).

KoolBak is the ONLY belt hand crafted in the USA with a LIFETIME Warranty and it is GUARANTEED not to cause muscle atrophy.

A proper fitting belt is extremely important for your satisfaction. Please refer to the sizing instructions on the right to get the proper fit for you.

As fate would have it, the morning after my belt arrived, I wrenched my back. I decided then to see just how good these belts were. I put on the belt and almost instantly the pain subsided. I couldn’t believe it. I then undid the KoolBak and the pain returned. I then put on my old elastic belt and the pain was still there. I put the KoolBak back on and the pain was relieved again. Normally it takes 3-4 days for my back to return to normal, but by the next day after wearing the KoolBak I felt fine. I am totally sold on these belts.
