ThermoSyphon®: the thermoregulation is more powerful than ever and is active at the front and back of the fabric. Keep warm when it's cold and stay cool when you sweat.


Retina: Precise body mapping system that optimises the efficiency of this technology by enhancing stimulation with strategically placed zones. 


Sweat Traps®: This system prevents sweat and enables efficient cooling. It absorbs sweat so it can evaporate thermodynamically. A film of sweat stays on the skin, but is thin enough not to be noticed.


3D BIONIC SPHERE®: This system leaves a thin layer of moisture on the skin without it bothering the skin. It wicks away excess sweat, enabling it to evaporate through the dynamic thermal layer. The unique patented 3D-BionicSphere® system preserves resources to help you perform better. Less energy is spent regulating body temperature, leaving you with more energy for exercise.
