This lightweight X-Bionic generation 4.0 jersey is a high-tech model for ambitious runners and includes the technological advantages of ultra-high-definition Retina® fabrication. The 3D Bionic Sphere® system plays a decisive role in thermoregulation with a shape-optimized surface on the chest and an extended area on the back. The Sweat Traps® balance temperature through evaporation with precision, and the Kidney Ribs inserts dense tissue to simultaneously isolate the kidney and pelvic area. Ideo-Waistband elevated waist and Shoulder-Flex-Zone in the shoulder area keep the shirt in place and prevent skin irritations.
