Optimize your energy management while running with the innovative X-BIONIC® EFFEKTOR® 4.0 RUN SHORTS WOMEN featuring an Ideo-Waistband, the running shorts of the new X-BIONIC-4.0 generation for the sporty woman. The energy released through earlier sweat cooling directly flows into your running performance. From your very first training session with these women's shorts, you will immediately feel the technological advantage of ThermoSyphon®, the latest development stage of the legendary, patented 3D Bionic Sphere® System. Another innovation is the manufacturing on precision machines with Retina® Ultra-High-Definition technology, which ensures greater efficiency and effectiveness of the functions. The integrated X-BIONIC® Partial Compression® applies gentle pressure on the skin through bridges. This protects you from premature muscle fatigue while maintaining the important cooling effect of sweat. Iso-Pads over the hip bone provide targeted insulation to protect the underlying organs from cold. The interaction of the Innerlap Airconditioning Zone®, a special cooling surface on the inner thigh, along with the Sweat Traps® support your performance with optimized moisture transport and cooling effect.
