X-Bionic Energy Accumulator 4.0 - Long Sleeve Undershirt

Captivates with thermoregulation and protection: the Energy Accumulator 4.0 long sleeve undershirt by X-Bionic

This high-tech underwear for winter sports enthusiasts combines a variety of thermoregulatory and protective properties. The legendary, patented 3D Bionic Sphere^® system with ThermoSyphon^® technology is more powerful than ever and works on chest and chest muscles. Complex 3D structures and Y-shaped elements maximize air exchange, cool when you sweat and warm when you freeze - now faster and more efficient than ever.

Functional zones such as the Air-Conditionig Channel^® and the AirComPlex zone in the upper abdomen as well as ISO shoulder and sweat traps^® under the arm are also performance-enhancing thermoregulatory technologies. Expansion Ribs^® at the elbows ensure optimum climate comfort and at the same time offer full freedom of movement. Partial compression supports the performance-enhancing effect while at the same time improving blood circulation for optimum cooling.

Technologies

3D Bionic Sphere® System with ThermoSyphon® Technology
The new 3D Bionic Sphere® system with ThermoSyphon® technology is characterized by complex 3D structures of the inner and outer air channels. It cools when sweating and warms when cold. Sweat Traps® absorbs perspiration and transports it to evaporation-efficient regions. This maximizes cooling and increases performance.

Air-Conditioning Channel®
The AirConditioning Channel® is a ventilation system of channels that wrap around the body, continuously carrying away moisture and warmth. It allows air to flow to body regions not normally accessible by fresh air circulation. Physiological studies have shown that e.g. the chest area is an optimal zone for quick and effective venting and cooling. Exchanging fresh air over a system of channels cools the chest area without spreading a “cold” sensation throughout the body. The constant air movement along the AirConditioning Channel® also effectively draws moisture away from the sweat zones.

ExpansionRibs™
The knitted fabric of the ExpansionRibs™ folds apart based on the accordion principle, insuring that cold doesn‘t cool down the elbows. Even when sharply bent, the insulating effect is maintained through warm air stored in the interior. The flexibility of the ExpansionRibs™ and the elasticity of the yarn allow a frictionless freedom of movement.

Air Guides^®
Spacers that work as side stops along the Air-Conditioning Channel^®.

AirComPlex-Zone
The AirComPlex-Zone protects the sensitive area on the solar plexus with special channels. Warm air enclosed there insulates perfectly in the cold. The system’s structure processes excess sweat from physical activity and ensures appropriate coolness in the core.

Aktiv-Bund®
The Aktiv-Bund® adapts to any size of arm, leg and hip without slipping or constricting.

IDEO-Waistband®
The ideally designed, ergonomically optimized waistband keeps the garment in place even with constant movements.

ISO-Shoulder™
The wavelike structure of the ISO-Shoulder™ lies over the shoulders, keeping the body warm and guarding against chills.

Sweat Traps™
Of the 3 million sweat glands in our skin, almost 300 per square centimeter are packed into the underarm area. Sweat Traps® wick away the moisture where it begins. The Evaporation Surface Expander™ processes sweat and pulls the moisture away.
