The Radiactor 4.0 Pants Gold/Black men's tights from X-Bionic are a technical base layer from the Energizer® range, developed and designed for all your sports performances in skiing, snowboarding, biathlon, or ski touring.
The thermoregulation provided by the 3D Bionic Sphere® technology combined with Thermsyphon® technology allows you to meet your body’s different needs by insulating cold-sensitive areas and ventilating zones where heat builds up, thus ensuring optimal sweat management.
Ergonomic, its Ideo-waistband is ideally designed with a high cut at the back to keep the base layer in place during physical exertion. The Expansion Ribs® at the knee provide comfort both thermally and in your freedom of movement.

| 3D BIONIC SPHERE® | The award-winning 3D Bionic Sphere® system stops unpleasant moisture, the feeling of overheating during intense activity, and prevents cooling during rest and recovery phases. |
| EXPANSION RIBS® | A highly flexible system of chambers and channels ensures insulation of the elbows by storing warm air inside, opening with each movement and releasing the stored warm air. |
| THERMOSYPHON® | The patented ThermoSyphon® structure adds an extra dimension to the special properties of the 3D Bionic Sphere® system: Y-shaped elements support natural thermodynamics and thus improve sweat management. |
