The new winter 4.0 generation collection from X-BIONIC offers performance and comfort in the most demanding conditions on the mountain, setting new standards in technology and performance that are aimed at ‘completely redefining performance apparel’.
The high-tech underwear for winter sports enthusiasts combines a variety of thermoregulating and protective properties. The new 4.0 generation is the first to offer Retina ultra-high-definition quality for unparalleled functionality for men and women.
The legendary patented 3D Bionic Sphere System with ThermoSyphon technology has been further improved and ensures the perfect performance climate on cold winter days. The technology maximises air exchange, cooling when sweating and warming when cold. As a result, less energy is needed to regulate body heat, so more energy reserves are retained for activities on the snow.
ENERGY ACCUMULATOR COLLECTION
4.0 SHIRT ROUND NECK LONG SLEEVE

The high-tech underwear for active winter sports enthusiasts combines a variety of thermoregulating and protective properties. The patented 3D Bionic Sphere System with ThermoSyphon technology is more powerful than ever and works on the chest and back. Complex 3D structures and Y-shaped elements maximise air exchange, cooling when wearers sweat and warming when freezing.
Functional zones such as the Air-Conditional Channel and the AirComPlex Zone in the upper abdomen, as well as ISO shoulder traps and sweat traps under the arm, are also among the performance-enhancing thermoregulating technologies. Expansion ribs on the elbows provide optimal climate comfort while offering full freedom of movement. Partial compression supports the performance-enhancing effect while improving blood circulation for optimal cooling.
4.0 MELANGE PANTS

For a targeted effect, intelligent functional zones in the ultra-dense knitted fabric can be positioned even more precisely. The patented 3D Bionic Sphere System with ThermoSyphon technology is more powerful than ever and acts on the chest and back; complex 3D structures and Y-shaped elements maximise air exchange, cooling when sweating and warming when cold.
Functional zones such as the Innerlap AirConditioning Zone on the inside of the thighs and the ISO-CalfPad in the calf area regulate the temperature and increase performance. The ExpansionKnee at the knee joint ensures optimal climate comfort and at the same time offers full freedom of movement.
4.0 ARMADILLO BASE LAYER 3/4 PANTS

The X-BIONIC ENERGY ACCUMULATOR 4.0 ARMADILLO is the world’s first cut- and abrasion-resistant performance ski underwear, developed together with Swiss-Ski and certified by the FIS to reduce injuries during winter training and competitions. The product protects athletes from injuries such as cuts and abrasions that can occur during falls on the slopes or in open terrain. In addition, the 3D structures help to wick away sweat and maintain a core body temperature of 37°C.
The protective material is only placed in exposed and endangered areas. This high-tech baselayer for winter sports enthusiasts integrates a variety of thermoregulating and protective properties. The legendary patented 3D Bionic Sphere System with ThermoSyphon® technology is more powerful than ever. Complex 3D structures and Y-shaped elements maximise air exchange, cool the body when sweating and warms when cold – now faster and more efficiently than ever.

Complex 3D structures and Y-shaped elements maximise air exchange, cool the body when sweating and warms when cold – now faster and more efficiently than ever.
Functional zones such as the Air-Conditioned Channel and AirComPlex Zone, as well as ISO-Shoulder and ISO-Chest Area, are also performance-enhancing thermoregulating technologies. Expansion ribs on the elbows provide optimal climate comfort while offering full freedom of movement.
X-SOCKS SKI SILK MERINO 4.0

With innovations from 20 years of experience, the X-SOCKS SKI SILK MERINO 4.0 offer protection, warmth and a temperature-controlled skin feel for winter sports. Intelligent functions ensure continuous thermoregulation, optimal moisture management and effective injury protection.
The unique Suppronation Bandage supports the foot and provides a secure fit. The new HeliXCoil system, integrated into the material, encloses the calf with two concentrically knitted spirals that have a stabilising effect on the muscles, promote blood circulation and reduce the risk of fatigue-related injuries.
The anatomically shaped footbed optimises the position of the foot and prevents overloading. Protective technologies such as heel, toe and shin guards provide maximum comfort and prevent the risk of injury from friction and impact.
TECHNOLOGIES
It was only after visiting X-BIONIC’s exceptional research, development and manufacturing facilities, plus talking with the academic bodies collaborating on product evolution and testing that it was possible to grasp the scale and depth of the company’s commitment to performance.
3D BIONIC SPHERE WITH THERMOSYPHON TECHNOLOGY
The revolutionary 3D BIONIC SPHERE THERMOSYPHON technology actively cools wearers when sweating and keeps them warm when the temperature drops. The 3D Bionic Sphere System leaves a thin film of moisture on the skin without the body noticing the wetness. Sweat traps then transport excess sweat, allow it to evaporate and dissipate it through thermal dynamics. All that remains is a pleasant, thin, cooling layer of moisture.
Evaporation occurs in three ways, activated by body heat:
– on the skin, for cooling
– in the sweat traps to process excess moisture
– in the Evaporation Surface Expander, where the excess eventually evaporates
Whether in extreme cold or unbearable heat, the 3D Bionic Sphere ensures the perfect performance climate. It cools when sweating and warms when cooling down. Excess moisture is continuously replaced and discharged by fresh air flowing in.
The patented and unique 3D Bionic Sphere System preserves important resources to maintain performance. It requires less energy to regulate body heat, so more energy reserves are retained for exercise. Cold ambient air does not pose a risk factor for hypothermia as the warm air inside the InnerAirChannels forms an insulating cushion.
In the recovery phase, the cooling process is interrupted by the absence of sweat. The air in both channels warms and protects by using the body’s own heat.
AIR-CONDITIONING CHANNEL – FRESH AIR CIRCULATION FOR MORE PERFORMANCE
Conventional thermal underwear fulfils a specific task: it keeps the body trapped in its own warmth, which can be a pleasant feeling up to a certain point but can quickly lead to overheating during physical activity. X-Bionic’s Air-Conditioning Channel is a re-imagined ventilation system that allows the body to breathe while continuously wicking sweat and heat away to the outside. It allows air to flow into areas of the body that are normally not accessible for fresh air circulation.
RETINA ULTRA-HIGH-DEFINITION QUALITY
Fine threads are processed into a dense fabric using high-precision machines. Depending on the desired effect, X-BIONIC varies the desired material density. As a result, the functional zones are placed more precisely and demarcated from each other. They don’t just work where they can, they work where they should.
As a result, the textile retina offers optimised function signalling and efficiency for better cooling and support. As with the millions of human retinal sensors on the eye, the material can process more information and signals directly from the skin and thus have a performance-enhancing effect.
