This is our latest generation, Far-InfraRed (FIR) 5 Volt – Powered Kidney Warmer, it utilises the latest Polymeric technology (NOT HOT WIRES!) ensuring it is Intrinsically safe, super-efficient and cannot overheat.
The outer is constructed from a soft feel, 3-layer membrane technical fabric, which ensures high thermal retention and all-Day wearer comfort. It also incorporates an Extra-large FIR heating element which heats to 45 degrees centigrade and is positioned to direct the deep penetrating gentle heat rays to the kidneys which in turn heats the surrounding blood vessels thus maintaining the wearers “core body temperature” vital in cold conditions.
The FIR warmer is powered by any 5v Powerbank. (not included)
