Award-winning X-Socks® and X-Bionic® Functional Sportswear are designed with proprietary fibers and fabric constructions to cool you when you’re sweating and keep you warm when it’s cold. Specific compression areas in both the socks and first layer garments ensure the necessary circulation and insulation you need when you’re pushing hard.
