Technologies and manufacturing processes

  • Air-Conditioning Channel®

    Traditional thermal underwear does one thing systematically: Keeps the self-produced heat longer on the body. This can be very pleasant, but from a certain activity level this can quickly lead to overheating of the body.
    Fresh air circulation for more performance.
    The permanent air movement along the Air-Conditioning Channel® effectively draws out and removes moisture from the sweat zones.
  • ISO-CalfPad

    Especially after short breaks, the calf muscles can already cool down, even if the entire body is still heated. This poses a risk of injury.
    Perfect isolation for your calves.
    The ISO-CalfPad retains body heat. By holding body warmth in special channels, the cooling of the calf muscles is decisively delayed and contributes to the body's overall sensation of warmth.
  • Innerlap AirConditioning Zone®

    The inner thighs are less cold-active in terms of muscle performance.
    Efficient cooling no matter what the conditions
    Air permeability is increased in this area through the Innerlap AirConditioning Zone®, the insulation layer is reduced, so air conditioning is strengthened by air exchange.
  • Expansion Ribs®

    Knees and elbows can bend up to 160 degrees. That hardly makes a wash with, without thinning out and thus losing the heat function.
    Freedom of movement and high insulation combined.
    The flexibility of the Expansion Ribs® and the elasticity of the yarn allow frictionless freedom of movement without the risk of cooling down.
  • InsulationPads

    The InsulationPads keep the thigh muscles warm. Severely hypothermic muscles can feel numb. But it becomes dangerous when the muscle reaction time slows down due to the cooling. Then not only muscle injuries threaten, but also the risk of accidents increases dangerously.
    Maintain your muscle power - always
    The X-BIONIC® InsulationPads assist in the retention of heat in the thighs and thus reduce the risk of injury.
  • AirConditioningSpot

    Since the back of the knees sweat quickly and heavily, a fine, round mesh fabric is incorporated there. With the help of body heat, excess sweat is pressed outwards, where it evaporates without the risk of cooling down.
    Cools the knee without the risk of cooling.
    The AirConditioningSpot cools without chilling.
  • ISO pads

    11 channels each form the ISO pads at the hips and even extend over the waistband. Large areas of the organs are thus protected from the cold. In winter, it is possible to protect the body from freezing by specifically insulating individual body parts from ambient cold. Thus the ISO pads over the hip bones and also the finer ISO pads on the buttocks keep the warmth on the body, which is necessary to guarantee the internal organ functions. At regular intervals, the ribs of the ISO pads drape over the shoulders, keeping warmth on the body and protecting against chilling. This is where a lot of heat is lost with conventional jackets, because the weight of the jacket or backpack compresses the insulation material so that it loses its effect.
    More insulation area
    ISO pads enable targeted insulation of individual body parts from a cold environment. By retaining body heat that is necessary to guarantee interior organ functions the temperature-regulating zones prevent the cooling down of the whole body.
  • Air Guides®

    Outerwear can lie heavily on the body and hinder the thermoregulation through functional underwear. In order to maintain the ventilation function, it is necessary to keep a distance between the functional and outer garments.
    Work like spacers and side stops along the Air-Conditioning Channels®.
    Work like spacers and side stops along the Air-Conditioning Channels®.
  • 3D Bionic Sphere® System with ThermoSyphon® Technology

    Depending on the ambient temperature, functional clothing must ensure reliable thermoregulation even when performance is sustained. Only an enlarged evaporation area and efficient sweat management guarantee an optimal skin climate even under load. The idea is to reduce sweat, not to prevent it.
    Unique and extremely effective temperature management.
    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.
  • Active-Bund®

    No clothing is more disturbing than the one that constantly slips, cuts in and hinders freedom of movement. This has to be prevented.
    Highly adaptable for perfect fit
    The highly elastic Aktiv-Bund provides a secure fit and support without constricting or impeding movement.
  • IDEO-Waistband

    During continuous movement, slipping functional underwear can lead to annoying friction. Only outstanding material and an optimal fit guarantee a performance-enhancing sense of well-being.
    Ideally designed, ergonomically optimized.
    The ideally designed, ergonomically optimised waistband, with higher cut in the back, keeps the garment in place even during constant movements.
  • ExpansionKnee

    A knee can bend up to 160 degrees. Hardly any pants can do that without thinning out and losing their thermal function. The accordion principle of the Expansion Ribs® gains insulating properties with the bending of the knee, instead of losing them. Highly flexible, a chamber and channel system unfolds with the movement, in whose interior warm air is stored for insulation.
    The ExpansionKnee protects the knee from the cold even in a bent position.
    The accordion-like construction of the ExpansionRibs® retains its insulating properties rather than losing them when the knee is bent.
  • Two-Step Front 3D Bionic Sphere® System

    An excess of sweat, which is not transported away by the functional underwear but accumulates unpleasantly on the skin, leads to irritation and limits the well-being, which is essential for optimal performance.
    Scientific solutions ensure at any time the optimal body temperature.
    The high-tech knitting technology ensures optimal support and climate comfort in the shorts. The varied ribbing and surface construction are able to solve the conflict between providing support whilst transporting moisture and heat.
  • Partial compression®

    Compression sportswear improves the supply of oxygen and nutrients to the muscles, reduces muscle vibrations and helps to speed up recovery. Large-area, mechanical pressure can negatively influence the blood circulation in the tissue. If no sweat remains on the skin, the blood cannot be cooled. This leads to a reduction in the functioning of the body's own cooling system.
    A new benchmark in compression technology.
    Partial Compression® applies targeted pressure on 1 mm-wide ridges. Left and right of the ridge is a compression-free area where compression could have a negative effect on blood circulation to the skin. In this way the blood flow through the veins and capillaries remains unimpended.
  • 3D Bionic Sphere® System

    The body sweats during activities. The natural cooling system keeps the body at an ideal 37°C by means of sweat. Traditional thermal underwear draws the cooling sweat away from the skin. This tempts the body to produce even more sweat. Valuable fluids, minerals and salts are lost without efficient cooling. This reduces performance.
    Cools when you sweat. Warms when you're cold.
    The award-winning 3D Bionic Sphere® System stops unpleasant moisture, the feeling of overheating during rigorous activity and prevents cooling during rest and recovery phases.
