The X-BIONIC XCEED RIDE JERSEY SH SL offers you unparalleled thermoregulation and is so lightweight that you can hardly feel it. The innovative HygroDiffuser with VectorSphere combines a highly sensitive moisture-wicking base with innovative 3D-knitted channels. The result is air pockets that store body heat in the absence of sweat, keeping you warm in cooler temperatures. As you heat up, they trigger a cooling reaction by distributing sweat over a larger surface area. This keeps your core body temperature optimally at 37°C, enhancing your athletic performance by conserving lost energy. For added comfort, the SweatVent system features lightweight mesh material in areas where you sweat the most, providing exceptional ventilation and a pleasant climate.
