THORNY DEVIL® technology collects excess sweat and directs it to large muscle groups, where it is evaporated at high speed, allowing them to be cooled down. THE TRICK® patented technology creates a zone of local heat in the spine. Sensors in the body transmit the sensation of warmth directly to your brain, causing your body to break into a sweat. The energy released by the earliest start of evaporative cooling directly influences your running performance. ThermoSyphon® System, the next generation of the legendary 3D Bionic Sphere® system optimizes the climate management of your skin. High-precision Retina® manufacturing, ultra-high definition technology.
