In the beginning there was a revolutionary functional sock. Then came an innovative jacket. Just like with evolution, the development was continually perfected and X-BIONIC® patents for leading solutions piled up. Long-standing beliefs about functional apparel ended up in the garbage due to outdated myths. In the place of bulky socks came anatomically shaped, multifunctional construction that maintains the barefoot climate found in nature. Instead of sweat-absorbing material came unique membranes that gave energy back to the body instead of absorbing it. From a technological viewpoint, X-BIONIC® is more at home in the aviation industry than in the world of sports clothing. Our engineers make use of high-tech research and innovative materials. No detail is superfluous, every fibre has a function, and every product is a sophisticated construction that integrates the body perfectly into its sporting environment.
