Warms the kidneys and lower back. Protects against wind and cold. Extra fluffy and warming inner lining. Additional support function ensures extra comfort. The Standard kidney warmer is one of three kidney warmers from our "back fit" series. In addition to the warming effect, it provides good grip for light back pain. Thanks to its support function, it reminds you of an upright posture and can help prevent poor posture. Thanks to the closure that sticks everywhere, the size can be individually adjusted.
