TWYCE® 4.0


Optimize your cycling performance with high-tech functional garments from X-BIONIC, the innovative world champion. With its anatomically optimized shape for female cyclists, the TWYCE 4.0 BIKE ZIP SHIRT SH SL WOMEN is part of the new X-BIONIC 4.0 generation.

It promotes natural skin-climate regulation with the 200% enlarged ThermoSyphon® system, the next generation of the patented 3D Bionic Sphere® system. It maximizes your cooling so you save energy and stay productive longer.

Dr. Sandra Ueckert, a researcher at the Technical University of Dortmund, explains that endurance athletes consume as much as 97% of their energy to maintain an optimal body temperature of 37° C. ThermoSyphon® cools your body when you sweat and warms it when you're cold. The complex 3D structure of air ducts and Y-shaped elements ensures maximum thermodynamics and is supported by other groundbreaking innovations such as the AircomplexZone on the chest and sweat-conducting structures all around.

This biking shirt delivers a new experience of enhanced wearing comfort and greater effectiveness thanks to the Dolphin Rider neck and seamless sleeves on the forearms.

The new Ideo-Waistband provides reliable support at the Waistband without constricting so everything stays perfectly in position even on long tours.

This shirt is a precision instrument for top performance thanks to manufacturing by highly precise state-of-the-art machines in Retina® ultra-high-definition quality. It offers significantly more effectiveness than X-BIONIC® products of the previous generation.
