Experience even more performance in your favorite sport with the X-BIONIC® INSTRUCTOR 4.0 TRANSMISSION LAYER JACKET MEN. The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for unique accuracy of functionality. For a targeted effect, intelligent functional zones can be positioned even more precisely in the ultra dense knitted fabric.

Feel the technological advantage of the legendary 3D Bionic Sphere® System: Greater cooling performance thanks to the 30% larger surface, which is anatomically positioned based on scientific research. It cools when you sweat and warms when you are cold, while preventing cool down or overheating. The Climate Fix System with its air-storing structures works similar to the 3D Bionic Sphere® System. It supports the body's own temperature management and prevents overheating and cooling.

This mid-weight transmission jacket with a full zip and regular fit is designed to offer the full advantage of thermoregulation without restricting freedom of movement. Enlarged Sweat Traps® balance the temperature through accurately targeted evaporation. For even more wellbeing the jacket is made of special, protected X-BIONIC® high-tech INTELLIYARNS®, which stop bacteria and odors.
