Product Description
100% power? You can do much more with double cooling. These X-BIONIC Twyce 4.0 Women's padded bib shorts from the X-BIONIC 4.0 generation increase your performance through superior regulation of skin climate. The key component is the ThermoSyphon System, the next generation of the 3D Bionic Sphere System, which has been enlarged by 200%. It cools you down when you sweat and warms you when you’re cold. In contrast to the legendary 3D Bionic Sphere system, the complex 3D structure of the inner and outer air ducts is now supplemented by Y-shaped elements. This further improves the natural thermodynamics of the system and significantly increases performance. The unique partial compression reduces fatigue, improves muscle control and nutrient supply - all without neglecting cooling. The high-quality integrated pad has a high shock absorption effect and is ergonomically pre-shaped to maximize comfort when cycling or turning. Thanks to the new X-BIONIC production quality in Retina Ultra High Definition Technology, these cycling shorts are a precision instrument for top performance. This cycling super sport clothing with comfortable straps is produced on the most modern, high-precision machines and accordingly offers you a much more effective density and effectiveness of all functions. The proven Innerlap climatic zone, the Intercooler, the SweatTraps and the ISO-Pad now work even more effectively than ever before.

3D-Bionic Sphere System
The 3D-Bionic Sphere System leaves the skin with residual moisture that the body does not feel as wet. There are no sensors for sweat. It’s only when drops form and run that we perceive "wetness" via this mechanical stimulus. Sweat Traps absorb this moisture before it can be felt, cause it to evaporate and dispose of it through the dynamics of heat. Back on the skin remains an imperceptible film of moisture that cools. Because: No sweat - no cooling.

The patented ThermoSyphon structure adds an extra dimension to the special properties of the 3D Bionic Sphere System: Y-shaped elements support the thermodynamics and thus improve sweat management.

The highly elastic active waistband ensures a secure fit and support without restricting or hindering movement.

Comfort4000FX bicycle pad
The Comfort4000 FX Bike Pad is anatomically shaped and adapts perfectly to the female anatomy. This relieves sensitive capillaries and nerves.

IDEO Federation
The ideally designed, ergonomically-optimised waistband with a higher cut at the back keeps the garment in place even with constant movement.

The targeted insulation of individual parts of the body against ambient cold can prevent the body from cooling down. For this reason, ISO pads store the necessary body heat via the hip bones to maintain the function of the internal organs.

Innerlap AirConditioning Zone
The inner thighs are less cold-responsive in terms of muscle performance. Instinctively, we know: there we can put our cold hands and warm them up to bring our overall warmth sensation into balance more quickly. The Innerlap AirConditioning Zone is located in this area. The air permeability is increased in this area, the insulation layer is reduced, so air conditioning is increased by air exchange.

This 3D construction collects sweat on the thigh and back, keeps it directly on the skin so that it can evaporate optimally. The rib technology of the Intercooler lies in an undulating structure on the muscle to ensure isolation. The trapped air protects the muscles from excessive cooling.

Sweat Traps
Excess moisture transport. Sweat forms a fine film of moisture on the skin. Drops are collected in the sweat traps and led to the evaporation surface expander. Evaporation takes place on three levels: On the skin to cool down, in the sweat traps excess moisture can be processed, on the Evaporation Surface Expander to final evaporation of excess moisture.

Twyce Cool Zone
In the chest area, back area and under the armpits. Hydrophilic and hydrophobic fibres absorb excess sweat from the 3D-BionicSphere system, pass it on and allow it to evaporate over a wide area to assist cooling.

X-Bionic Partial Compression
X-Bionic partial compression takes advantage of compression without neglecting cooling. Sport generates heat. In extreme situations up to 1,200 watts. The athlete releases 90 % of these through the skin and thus maintains his body temperature at 37 °C. The X-Bionic partial compression exerts pressure in a targeted manner via 1 mm thick bars. To the left and right of this, a pressure-free zone is created without the application of mechanical pressure, which could have a negative effect on the skin's blood circulation. The blood vessels remain open. Partial compression takes the skin into account as a cooling surface and can thus optimise the human climate balance for better performance.
