The X-BIONIC XCEED RUN SHIRT SS is not only a fashion statement but also a technological masterpiece that elevates your performance to a new level. With the HygroDiffuser and VectorSphere, the shirt offers unparalleled thermoregulation. This innovative technology combines a highly sensitive, sweat-wicking base with 3D-knitted channels. The result is air pockets that store body heat when there is no sweat, keeping you warm in cooler temperatures. As you heat up, the system triggers a cooling reaction by distributing the sweat over a larger surface area. The X-BIONIC XCEED RUN SHIRT SS helps you maintain your optimal core temperature of 37°C. This saves the energy that would otherwise be lost and enhances your athletic performance.
