Description

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.

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.
