Description

The brand's first X-Bionic layer Radiactor 4.0 Round Neck LS Gold/Black for men is a technical base layer from the range Radiactor®, developed and designed for all your sporting activities in extreme cold, including skiing, snowboarding, biathlon and ski touring.

Thermoregulation provided by the technology 3D Bionic Sphere® and reinforced by the new technology Thermosyphon®meets the body's various needs: to insulate areas sensitive to cold and to perform ventilation in areas where heat accumulates, ensuring optimal perspiration management.

The technology keeps AirComPlex-Zone you warm at the solar plexus, and the technology Expansion Ribs® provides increased insulation in sensitive areas such as the elbows. It is designed using a high-tech fibre XITANIT®2.0 that reflects heat in an even more sophisticated way. With silver ions to make it bacteriostatic, XITANIT® it optimizes perspiration management by distributing perspiration and optimizes cooling through evaporation. This actively helps to remain competitive.

3D BIONIC SPHERE®	The award-winning system 3D Bionic Sphere® stops unpleasant moisture and the feeling of overheating during intense activity, and prevents cooling during rest and recovery phases.
XITANIT®	High-tech fibre that reflects heat even more effectively.
ISO SHOULDER	ISO-Shoulder forms an insulating layer that prevents the cold from getting in. Exceptional protection against the cold of upper body clothing.
EXPANSION RIBS®	A highly flexible system of chambers and channels insulates the elbows by storing warm air inside, opening with each movement and releasing the warm air stored inside.
THERMOSYPHON®	The patented ThermoSyphon^® adds an extra dimension to the special properties of the 3D Bionic Sphere^®: Y-shaped elements support natural thermodynamics, improving perspiration management.
AIRCOMPLEX ZONE	The warm air trapped in special channels insulates the solar plexus optimally in cold weather. During physical exertion, the structure evaporates excess sweat and provides a good feeling of freshness.
RETINA®	Offers ultra-high definition texture, ultra-high density function transmission, and ultra-high precision body zoning. The result is an ultra-dense knitted material with reduced volume that offers full functionality at a pleasantly low weight.
