TECHNOLOGY

• 3D Bionic Sphere System: The award-winning 3D Bionic Sphere® System stops unpleasant moisture, the feeling of overheating during rigorous activity and prevents cooling during rest and recovery phases.
• Air-Conditioning Channel: The permanent air movement along the Air-Conditioning Channel® effectively draws out and removes moisture from the sweat zones.
• Sweat Traps: Large dimensioned sweat traps, ergonomically positioned based on laboratory tests, prevent the moisture from dripping and provide active cooling.
• Expansion Ribs: The flexibility of the Expansion Ribs® and the elasticity of the yarn allows frictionless freedom of movement without the risk of cooling down.
• AirComPlex-Zone: The AirComPlex-Zone protects the sensitive area on the solar plexus with select 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.
• ISO-Shoulder: ISO-Shoulder forms an insulating layer to keep penetrating cold at bay—outstanding protection against chilling upper-body garments.
• Air Guides: Work as spacers and side stops along the Air-Conditioning Channels
• 3D Bionic Sphere System with ThermoSyphon Technology: The patented ThermoSyphon® structure adds an extra dimension to the unique properties of the 3D Bionic Sphere® system: Y-shaped elements support natural thermodynamics and thus improve sweat management.
• Aktiv-Bund: The highly elastic Aktiv-Bund provides a secure fit and support without constricting or impeding movement.
• IDEO-Waistband: The ideally designed, ergonomically optimised waistband, with a higher cut in the back, keeps the garment in place even during constant movements.
