The X-Bionic Twyce 4.0 G2 Bike bib shorts are designed to increase your performance thanks to a superior regulation of the skin climate.

• In the center: a latest generation 3D bionic sphere system, called ThermoSyphon, enlarged to 200%. It cools when you sweat and warms when it's cold. Unlike the legendary 3D Bionic Sphere System, the complex 3D structure of the internal and external air channels is now complemented by Y elements. They also improve natural thermodynamics and thus enable a noticeable increase in performance.
• The unique PartialCompression reduces fatigue, offers greater muscle control and improves nutrient supply. All this without neglecting cooling.
• For added comfort when pedaling or spinning, the high-quality integrated pad has a high cushioning effect and is ergonomically preformed.
• The highly elastic and breathable braces rest perfectly on the skin without cutting.
• Reflective logo for better visibility.
• Self-adjusting active edge fits the leg without slipping or squeezing.
• Sporty and tight fit.
• Color: Black/White.
