X-Bionic Energizer 4.0 long-sleeved cycling base layer

Experience the soothing effect of high-tech base layers that are both lighter yet still highly functional! The X-Bionic Energizer 4.0 base layer meets all the expectations of the most demanding cyclists, who enjoy exceptional comfort and thermal regulation that optimises performance.

The new generation of 4.0 technical base layers incorporates 13 technologies for unfailing effectiveness. The functional zones that regulate temperature are precisely positioned and support your performance on cooler days without compromising comfort.

The legendary patented 3D Bionic Sphere system with ThermoSyphon technology is more powerful than ever and is active across the chest: A 40 cm² sweat-absorbing surface, along with complex 3D structures and Y-shaped elements, maximises airflow, cooling you when you sweat and warming you when you’re cold more quickly and efficiently than ever before.

Technologies such as the AirComPlex-Zone on the upper abdomen and the Air-Conditioning Channel with surrounding Air Guides provide ventilation that effectively regulates temperature under a second layer of clothing.

In short, if you’re looking for a high-tech, top-quality long-sleeved cycling base layer, this product is for you!
