X-Bionic athletic apparel is the most advanced performance clothing on the planet. X-Bionic holds over 20 patents for performance-enhancing technologies. Long story short, X-Bionic socks and athletic apparel help athletes maintain a constant core body temperature. X-Bionic fitness apparel ensures less energy is wasted cooling the body and more energy is therefore available to maximize athletic performance. Recent X-Bionic studies have shown that athletes can expend up to 97% of their metabolic energy maintaining their core temperature. X-Bionic apparel literally "turns your sweat into energy" by maximizing the human cooling mechanism of evaporation. X-Bionic gear makes more energy available for peak athletic performance through the use of superior science and materials, including Fennec® Reflective Fabric and AirGuides channels, as well as construction features like Underarm SweatTraps and the 3-D-BionicSphere® system.
