Technical long-sleeve T-shirt - Men -
The first layer Radiactor 4.0 Round Neck LS Gold/Black for men from the brand X-Bionic is a technical base layer from the Radiactor® range, developed and designed for all your sporting performances in skiing, snowboarding, biathlon or ski touring, in extreme cold.
The thermoregulation ensured by the 3D Bionic Sphere® technology and enhanced by the new Thermosyphon® technology, meets the body’s various needs: insulating areas sensitive to the cold and ventilating zones where heat accumulates, ensuring optimal sweat management.
The AirComPlex-Zone technology keeps you warm around the solar plexus, and the Expansion Ribs® technology provides increased insulation in sensitive areas such as the elbows. Its design is made from a high-tech fibre XITANIT®2.0 ensuring a highly technological fibre that reflects heat in an even more refined way. With silver ions to make it bacteriostatic, XITANIT® optimises sweat management by distributing perspiration and enhances cooling through evaporation. This actively helps you stay competitive.




- Targeted and partial compression to stimulate muscle function
Composition:
- 63% Polyester, 32% Polypropylene, 5% Elastane
| 3D BIONIC SPHERE® | The award-winning 3D Bionic Sphere® system stops unpleasant moisture, the sensation of overheating during intense activity, and prevents cooling during rest and recovery phases. |
| XITANIT® | High-tech fibre reflecting heat, further perfected. |
| ISO SHOULDER | ISO-Shoulder forms an insulating layer to prevent cold from penetrating. Exceptional protection against the cold for upper body garments. |
| EXPANSION RIBS® | A highly flexible system of chambers and channels ensures elbow insulation 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. |
| AIRCOMPLEX ZONE | Warm air trapped in special channels optimally insulates the solar plexus in cold weather. During physical effort, the structure manages excess sweat and provides a good feeling of freshness. |
| RETINA® | Offers an ultra-high definition texture, ultra-high density function transmission, and ultra-precise body zoning. The result is an ultra-dense knitted material with reduced volume that provides complete functionality at a pleasantly low weight. |
