X-Bionic Energizer 4.0

Experience the soothing effects of lightweight yet highly functional high-tech underwear. The X-BIONIC® Energizer 4.0 Pants 3/4 Men meet the demands of discerning winter sports enthusiasts with their moderate compression, while also providing outstanding comfort and performance-enhancing thermoregulation.

The new 4.0 generation is the first to offer Retina® Ultra-High-Definition quality for unique functional precision. The result is an ultra-dense knit that integrates 13 highly effective technologies. Functional zones with temperature-regulating and protective effects are precisely positioned to support your performance on cool winter days without feeling constricted.

The legendary patented 3D Bionic Sphere® System with ThermoSyphon® technology is more powerful than ever: complex 3D structures and Y-shaped elements maximize air exchange, cooling when you sweat and warming when you are cold – now faster and more efficiently than ever.

Functional zones such as the Innerlap AirConditioning Zone® on the inner thighs and Sweat Traps® for targeted management of excess sweat regulate temperature and enhance performance. The ExpansionKnee at the knee joint ensures optimal climate comfort while providing full freedom of movement.
