The X-BIONIC XCEED RUN SHORT TIGHTS are equipped with innovative HygroDiffuser and VectorSphere technology, providing unparalleled thermoregulation and elevating your performance to a new level. The highly sensitive moisture-wicking base of the HygroDiffuser, combined with the innovative 3D-knitted VectorSphere channels, creates air pockets that retain your body heat when there is no sweat, keeping you warm in cool temperatures. As you heat up and start to sweat, the system triggers a cooling reaction by distributing sweat over a larger surface area. Your core temperature remains optimally at 37°C, enhancing your athletic performance by conserving energy that would otherwise be lost.
