Product Details

For automobile owners, the "MK" marking system may just mean a simple model number. For the team of developers, though, these two letters alone represent months or even years of painstaking work and innumerable tests. The strategic focus is not just the design, but rather is more performance enhancements of the product: More horsepower, larger capacity, better chassis. In the end, of course, it's all about higher speeds and better safety. That's exactly the philosophy of X-BIONIC®. Superior products, like the BIONIC Energizer™, aren't just replaced, rather they are constantly improved. Our Swiss textile engineers needed months and months in the research laboratory together with our performance athletes. They focused mostly on the athlete, not on the product.

X-Bionic Energizer MK2 Light Sleeveless Running Top

3D Bionic Sphere® System

Cools you down when you sweat. Warms you up when you're cold. The 3D Bionic Sphere® System keeps your calves at an optimum performance temperature.


144 cm² more insulation. At the solar plexus, directly under the 12th thoracic vertebrae, important nerve fibres receive signals that influence one's entire well-being. The Energy Accumulator® EVO protects this sensitive area with special channels. Warm air enclosed there insulates optimally in the cold. The system's structure processes excess sweat from physical activity and ensures appropriate cooling of the core.


The knee hollow perspires quickly and heavily. A fine, circular knitted fabric has been incorporated there. Perspiration dissipates and is pushed outward with the aid of body warmth without the risk of chilling.

3D-BionicSphere® System On The Back

Guarantees effective ventilation so moisture is quickly wicked and transported away. No sweat means insulating air pockets in the wavelike structure protect against cold.

SweatTraps® On The Back

To make sure you don't waste one single drop of valuable sweat, the closely aligned rows of SweatTraps® now form the bottom of the 3D-BionicSphere® System on the back.

Air-Conditioning Channel®

The Air-Conditioning Channel® is a ventilation system of channels that flow around the body, continuously carrying away moisture and warmth. It allows air to flow to body regions not normally accessible by fresh air circulation.


  • 3-D BionicSphere System - Regulates body temperate in various weather conditions.
  • AirComPlex-Zone - Offers superb insulation, thermo regulation and much needed warmth provided to the vertebrae.
  • AirConditioning Spot - Fine knitted fabric which helps to regulate body temperature.
  • 3-D BionicSphere Back Area - Effective ventilation guaranteed, quickly wicks moisture for a cool and dry wear.
  • Air-Conditioning Channel - Carries cool air around the body at the same time as wicking moisture.
  • Self-Adjusting Cuff - Keeps the shirt from slipping up or constricting.
