Men's thermal shirt X-Bionic Energy Accumulator 4.0 red/white EAWT44W19M (EAWT44W19M)

Men's thermal long sleeve X-Bionic Energy Accumulator 4.0 is the pinnacle of innovation in sportswear, perfectly combining functionality with national spirit. 

X-Bionic Energy Accumulator 4.0, in the colors of Austria, is not only an expression of national pride but above all a support for athletic performance. The Patriot edition of the Energy Accumulator 4.0 line is more than just thermal underwear. It is an innovative design that, thanks to the use of X-BIONIC Partialkompression® zonal compression and 15 patented technologies and functions, improves athletes' performance. These solutions provide optimal conditions for the body, both during intense efforts and moments of rest.

The key technologies that distinguish this product include primarily THERMOSYPHON®, an evolution of the 3D Bionic Sphere® system. It provides a larger evaporation surface, which translates into faster sweat removal and maintaining optimal body temperature. Thanks to this system, the shirt cools down when the outside temperature is high and warms up when it is cooler. This intelligent body temperature management is crucial for maintaining high performance over a long time.

Sweat Traps®, Air-Conditioning Channel®, Air Guides®, and AirComPlex-Zone are additional technologies that guarantee optimal air circulation, thus controlling moisture and body temperature. Expansion Ribs®1 and Aktiv-Bund are technologies that increase comfort and flexibility, adapting to body movements without restricting freedom.
