X-Bionic Men Merino Pants

The new Generation 4.0 features Retina ultra-high definition quality for unparalleled functional accuracy for the first time. The patented 3D Bionic Sphere System with ThermoSyphon technology is more powerful than ever and is active at the front and the tailbone: Complex 3D structures and Y-shaped elements maximize air exchange, cooling when you sweat and warming when you are cold. Functional zones such as the Innerlap AirConditioning Zone and the InsulationPads, as well as the AirConditioningSpot and ISO-Pads, are also performance-enhancing, thermoregulating technologies.
