Proven technology

The KÜLKUF wristband has been proven to enhance performance, power, and recovery

KÜLKUF is powered by patented ClimaCon® technology. ClimaCon® technology incorporates novel and efficient heat transport mechanisms that remove/add heat to provide thermal comfort to the body. It works on the principles of the Peltier effect, embedding a thermoelectric unit with the geometrically optimized heat sinks. A highly efficient thermoelectric unit accompanied by high heat transfer coefficients is the engine that drives the system.
