X-Bionic Women Invent FX Pants

These trousers use intelligent regulation to prevent overheating so you always feel comfortable, even during intense workouts.
The innovative RETINA ultra-high definition technology ensures an unrivalled fit and feel. You'll hardly notice you're wearing them, the material is so light and soft against your skin.
The new 3D Bionic Sphere System keeps your skin temperature in the ideal range at all times. It dissipates excess heat when you start to sweat and keeps you warm when it's cold outside. So you can concentrate fully on your winter sports activities without having to worry about your well-being.
