The AirComPlex zone protects the sensitive area of the solar plexus with special channels. The warm air trapped there provides perfect insulation against the cold. These revolutionary pants are perfectly tailored to the needs of winter sports enthusiasts, keeping you warm when you're cold and cooling you down when you're warm. The 3D Bionic Sphere System with Thermosyphon technology ensures optimal body temperature, no matter how intense your training is. Excess sweat is quickly drawn away from the skin, providing a pleasantly dry wearing experience. The ISO-Shoulder function creates an insulating layer that protects you from penetrating cold. This allows you to fully focus on your athletic performance without being distracted by the cold. The Expansion Ribs ensure that the insulating properties are maintained even when limbs are bent. This keeps joints and ligaments optimally temperature-regulated, even during intense physical activity.
