X-BIONIC Twyce Race: double the cooling, double the performance. These high-end shorts are ideal for ambitious runners and trail runners who aim for peak performance even in the hottest conditions. These innovative shorts, with their precise fit, moderate compression, and cutting-edge X-BIONIC technologies, keep you cool so you can feel comfortable while running in the summer. Your keys or other small items are securely stored in the hidden zip pocket. The Y-shaped Twyce Cool Zones, combined with the 3D Bionic Sphere System and ThermoSyphon structure, wick moisture away from the skin and transport it to areas where it can evaporate quickly. The result? Optimal cooling for increased endurance and intensity while running. The Twyce Race 2-in-1 shorts counteract muscle fatigue with moderate partial compression, allowing them to withstand the greatest stresses. This effective technology maximizes your performance without restricting your movement.
