X-BIONIC Radiactor 4.0 base layer pants

Trust the outstanding thermoregulating effect of X-BIONIC® RADIACTOR 4.0 PANTS WOMEN even in extreme cold, while enjoying the incomparable comfort of a super-light fabric.

The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for unique accuracy of functionality.

The result is an ultra-dense knitted material with a reduced volume that offers full functionality at a pleasantly low weight.

Functional zones with thermoregulating and protective effects are positioned precisely and promote your performance and endurance.

The material owes its powerful temperature control effect on cold winter days to XITANIT® 2.0, an even more perfected, heat-reflecting high-tech fiber.

The legendary patented 3D Bionic Sphere® System with ThermoSyphon® technology is more powerful than ever and additionally supports the highly adaptive thermoregulation:complex 3D structures and Y-shaped elements maximize air exchange, cool when you sweat, and warm when you freeze - now even faster and more efficiently than ever before.

X-BIONIC® Partialkompression® uses targeted compression to stimulate muscle function, increase your performance and shorten recovery times.

Expansion Ribs® cushion the joints at the elbows and knees providing a warming effect even when the joints are in motion.
